The title compound,C 12 N 2 O 4 H 14 (M r=250.3),crystallizes in triclinic P1 space group with a=7.7709(9),b=8.7534(11),c=9.6958(12),α=77.103(2),β=80.496(2),γ=86.726(2)o,V=633.9(1) 3,Z=2,F(000)=26... The title compound,C 12 N 2 O 4 H 14 (M r=250.3),crystallizes in triclinic P1 space group with a=7.7709(9),b=8.7534(11),c=9.6958(12),α=77.103(2),β=80.496(2),γ=86.726(2)o,V=633.9(1) 3,Z=2,F(000)=264,D c=1.311 Mg/m 3,μ(MoKα)=0.1 mm-1,the final R=0.056,and wR=0.15 for 2239 observed reflections (I 2σ(Ⅰ)).The molecules in the crystal are linked through O-H···O type of hydrogen bonding interaction forming an infinite chainlike structure.The phenylhydrazone ring and oxobutanoate groups are almost planar.The keto hydrazo group adopts a Z-configuration in the molecule and the torsion angle is-177.6(2)°. 展开更多

The title compound dichloro tris(triphenyl phosphine oxide)cadmium(II) were grown by slow cooling method from aqueous solution. The title compound was synthesized and purified by repeated crystallization process. Grown crystals were characterized by X-ray diffraction and FTIR analysis. The range of optical transmission was determined by recording UV-Vis-NIR spectrum. Thermal properties were investigated by DTA and TGA analyses. Its mechanical hardness was estimated by Vickers microhardness method. 展开更多
