The crystal structure analysis of dioxo (2,2'-(1,2-phenylenebis (nitrilomethylodyne)) bis-(methoxy) phenoloto) (2-)-N,N',O,O') uranium and 4-(2,4,6-trimethoxy benzylidene)-2-phenyloxazolel-5-one compounds

Moleculer and crystal structures of Dioxo (2, 2' ? (1, 2 ? phenylenebis (Nitrilomethylodyne)) bis ? (methoxy) phenoloto) (2 ? ) ? N, N', O, O') uranium and 4 ? (2, 4, 6 ? trimethoxy benzylidene) ? 2 ? phenyloxazolel ? 5 ? one have been determined by single crystal X-ray diffraction method. Uranium complexes is in triclinic crystal system and P-1 space group. The non-hydrogen atoms were refined anisotropically.Reliability factor is found as R=0.037. There is two dependent molecule in the assmetric unit. The crystal structure is dimeric stabilized by interactions the C-H...O and O-H...O type. Azlacton structure is in triclinic crystal system and P-1 space group. The crystal structure of distances and angles are in consistent with the literature. Oxazolon and fenil rings are almost planar. Crystal structure is stable withine van der Waals interactions inaddition with C-H...O type intra and inter molecular weak interactions.
