dc.description.abstractSintetisana su dva derivata fenitoina (5,5-difenilhidantoina) i određene su njihove kristalne strukture. Urađena je kvantitativna analiza kristalnog pakovanja sa aspekta međumolekulskih interakcija i strukturnih motiva. Kristalno pakovanje 3-izopropil-5,5-difenilhidantoina sadrži centrosimetrične dimere povezane parom N–H∙∙∙O vodoničnih veza koji se dalje umrežavaju pomoću C–H∙∙∙O interakcija i paralelnih interakcija između fenilnih prstenova na velikom rastojanju u lance paralelne s-osi (slika 1). Osnovna karakteristika kristalne strukture 3-ciklopropil-5,5-difenilhidantoina jesu lanci koji nastaju preko N–H∙∙∙O vodoničnih veza, C–H∙∙∙O i C–H∙∙∙π interakcija (slika 2). Predstavljeno istraživanje daje uvid u ulogu međumolekulskih interakcija u kristalnom pakovanju proučavanih jedinjenja, kao i dalje smernice za dizajniranje novih derivata fenitoina sa poboljšanim farmaceutskim svojstvima.

dc.description.abstractTwo derivatives of phenytoin (5,5-diphenylhydantoin) were synthesized and their crystal structures were determined. The quantitative analysis of the crystal packings in terms of the contributing intermolecular interactions and structural motifs has been done. The crystal packing of 3-isopropyl-5,5-diphenylhydantoin contains centrosymmetric dimers linked by paired N–H∙∙∙O hydrogen bonds which further self-organize through pairs of C–H∙∙∙O interactions and a parallel interaction of two phenyl rings at a large offset into chains running along the c-axis (Figure 1). The principal feature of the crystal structure of 3-cyclopropyl-5,5- diphenylhydantoin is formation of the chains by N–H∙∙∙O hydrogen bonds, C–H∙∙∙O and C– H∙∙∙π interactions (Figure 2). The presented investigation provide not only new insight into the role of intermolecular interactions in the crystal packing, but also guidance for furthering crystal engineering to design novel hydantoin derivatives with improved pharmaceutical properties. Crystal data for 3-isopropyl-5,5-diphenylhydantoin: C18H18N2O2, triclinic, P–1, a = 8.5357(9), b = 8.6225(8), c = 12.3979(9) Å, α = 104.010(7), β = 91.826(7), γ = 115.201(10) °, V = 791.54(14) Å3 , R1 = 0.0473. Crystal data for 3-cyclopropyl-5,5-diphenylhydantoin: C18H16N2O2, monoclinic, P21/c, a = 11.5996(5), b = 10.6459(3), c = 12.2992(5) Å, β = 101.977(4) °, V = 1485.74(10) Å3 , R1 = 0.0403.sr
