AB  - High field magic-angle spinning (MAS) (31)P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O4 and PO4 tetrahedra. The MAS NMR spectrum of cobalt-containing products exhibits a large anisotropy manifested in numerous side bands. This effect is attributed to paramagnetic shifts induced by dipolar interactions between the unpaired electrons of Co(2+) and the (31)P nuclei. The relative intensity of the side bands is significantly lower in the cobalt-exchanged sample (where the Co(2+) does not occupa framework sites) than direct evidence of extra-framework cobalt(II) or of Co(II)  incorporation in the zincophosphate lattice.

AB  - A model system structurally based on CoAPO-21 has been studied by the PM3 MO method in order to examine the conformation of the encapsulated template species. It is confirmed that the observed conformation of the template ethylenediammonium ion in the framework  cavities corresponds to the energy minimum for the system. The spatial position of the hydrogen atoms of the template has also been estimated. The geometry of the ion should be primarily attributed to steric factors. Intra-molecular hydrogen bonding between template and the aluminophosphate lattice occurs through the N-H...O bonds that vary in strength due to steric reasons.

AB  - The reaction of a 1:3 molar mixture of the monosodium salt of 4-sulfophthalic acid and phthalic acod, carried out in the presence of NH4Cl, urea, CuSO4 5H2O, and (NH4)2MoO4, does not yield the mono-substituted derivative, i.e., the sodium salt of copper-phthalocyanine-4-sulfonic acid (mSCuPc) but a 1:3 mixture of tetrasodium salt of copper-phthalocyanine-4-sulfonic acid-4,4',4'',4'''-tetrasulfonic acid (tSCuPc) and copper phthalocyanine (CuPc). However, quantum-mechanical calculations indicate that mSCuPc should be energetically favoured over the equivalent mixture of tSCuPc and CuPc. The preferential formation of the latter mixture has been attributed to kinetic factors arising from simultaneous presence of ionic and covalent species in the reaction medium.

AB  - Hydrothermal synthesis of SAPO materials using isopropylamine (i-PrNH2) as the template leads to the formation of MnAPSO-34 if Mn(II) is present. In the presence of Cr(III), the synthesis yields SAPO-34 containing chromium(III), which is not incorporated in the silicoaluminophosphate lattice. Calcination of MnAPSO-34 results in oxidation of Mn(II); the calcinated product can be subsequently reduced back to MnAPSO-34.

AB  - Hydrothermal synthesis of CoAPSO-44 in the presence of cyclohexylamine (CHA) as the template is generally accompanied by the formation of an unknown phase, “Co(APSO)N.” Electronic spectroscopy indicates that CO(APSO)N contains Co2+ in a pentacoordinated environment. When Co(APSO)N is heated at 195°C in a water suspension under autogenic pressure, two processes occur: (a) a partial conversion of Co(APSO)N into CoAPSO-44 and (b) decomposition of Co(APSO)N into Co- and Al-phosphates. Thermal removal of CHA from Co(APSO)N results in a breakdown of the latter's cyrstal lattice.

AB  - The SAPO, MeAPO and MeSAPO microporous materials (Me=Co2+ and/or 2n2+) having a sodalite structure have been obtained hydrothermally at 200°C in the presence of tetramethylammonium ion as the template. The SAPO and MeSAPO products prepared at lower template concentrations are formed through a partial replacement of both aluminium and phosphorus by silicon in the parent aluminophosphate lattice; at higher pH only phosphorus is replaced. While the Me2+ ions are in all cases constituents of the framework, most zinc-containing materials have a fraction of the Zn2+ ions located in the cavities. T.g.a . shows that complete removal of the trapped organic component can not be easily accomplished. This can be explained by the small size of the openings in the sodalite cages. Powder diffraction analysis shows that replacement of aluminium by silicon, cobalt and zinc, and phosphorus by silicon leads to an expansion of the parent aluminophosphate unit cell. Kinetic studies suggest that crystallization of the silicon-containing products is preceded by an induction period of about 2 h, the nucleation taking place both in the liquid and solid phase.

AB  - Two materials, AIPO4-15 and CoAPO-15, with the same aluminophosphate lattice have been obtained by hydrothermal synthesis in the presence of hexamethylenetetramine (HMTA). Their formation is attributed to the influence of species that arise through the decomposition of HMTA, the latter process taking place under synthetic conditions. The Co 2+ ion in CoAPO-15 occupies tetragonally deformed octahedral sites, and this causes a slight expansion of the unit cell of CoAPO-15 in comparison to that of AIPO4-15. The Co 2+ ion is coordinated not only by the O atoms of the system but also by NH3 molecules.

CoSAPO-14 is a new MeSAPO material that predominantly forms at 125°C, whereas CoSAPO-34 is the main product at 160°C. CoSAPO-14 has a triclinic and CoSAPO-34 has a trigonal unit cell. Both materials contain in their cavities a template that is hydrogen-bonded to the lattice. The synthesis in the presence of Co 2+ ions is much more sensitive to the composition of the reaction gel than is usually found in the preparation of SAPO materials.

Reaction (1) is H2O concentration dependent and its rate constant increases from 0.088 to 1.88 h−1 as the H2SO4 concentration changes from 18 to 16 mol dm−3. The rate constant of (2) does not vary significantly with H2SO4 concentration and lies around the 0.05 h−1 mark. The CuPc formed in reaction (2) does not decompose under the above conditions.

AB  - Amorphous aluminosilicates containing about 12 wt.%  nickel have been synthesized by cation exchange. Approximately 40 % of the nickel content is present in the form of octahedral [Ni(H20)6]2+ ions while the bulk of Ni2+ is coordinated both by H2O molecules and by oxygen atoms of the aluminosilicate framework. When the materials are heated in air at 350 oC, a change in the nickel coordination environment/geometry and possibly also a partial oxidation take place.
AB  - Amorfni aluminosilikati sa oko 12 mas. % nikla dobijeni su jonskom izmenom. Oko 40% nikla nalazi se u obliku oktaedarski koordiniranih jona [Ni(H20)6]2+, a preostali nikal koordiniran je sa molekulima vode i kiseonikovim atomima iz aluminosilikatne rešetke. Zagrevanjem na vazduhu, na oko 350 0C dolazi do promena u koordinaciji, odnosno geometriji nikla, a moguće je da dolazi i do delimične oksidacije nikla.
