| Abstract: One complex{Cd(phen)[(C6H5)2C(OH)COO]2}2·H2O has been synthesized with benzilic acid and 1,10-phenanthroline. The crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to a triclinic system with space group P1, a=1.180 19(11) nm, b=1.194 48(14) nm, c=1.327 94(12) nm, α= 107.992 0(10)°, β=95.467 0(2)°, γ=99.128 0(10)°, V=1.737 1(3) nm3, Dc=1.446 g·cm-3, Z=1, F(000)=770. Final R1=0.032 5, wR2=0.066 0, GooF=1.094. The crystal structure shows that the cadmium(Ⅱ) ion is coordinated with four oxygen atoms from three benzilic acid molecules and two nitrogen atoms from one 1,10-phenanthroline molecule, respectively, forming a distorted octahedral coordination geometry. It is interesting that there are coordination hydroxyl oxygen atom and dentate bridge coordination carboxyl oxygen atom of the benzilic acid radical in the title complex. One parallelogrammic geometry Cd202 is formed by two dentate bridge coordination carboxyl oxygen atoms and two cadmium(Ⅱ) ions in the complex molecule. The luminescence property of the complex is also studied. CCDC: 716599. |
