摘　　要：羧酸配合物在配位化学中占有重要地位。羧酸配合物有丰富的拓扑结构、较高的稳定性，在磁学、光学、催化、生物等诸多领域有广泛的应用前景，羧酸配合物引起了人们广泛的兴趣和极大的关注^[1-3]。近年来，我们用小位阻的羧酸配体合成了一些羧酸配合物^[4-6]，而对于大位阻的羧酸配体体系我们研究很少。One complex {Cd（phen）[（C6H5）2C（OH）COO]2}2·H2O has been synthesized with benzilie acid and 1,10-phenanthroline. The crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to a tficlinic system with space group P^-1, a=1.18019（11）nm, b=1.19448（14） nm, c=1.32794（12）nm, α=107.9920（10）°,β=95.4670（2）°,γ=99.1280（10）°, V=1.7371（3）nm^3, Dc=1.446g·cm^-3, Z=1, F（000）=770. Final R1=0.0325, ωR2=0.0660, GooF=1.094. The crystal structure shows that the cadmium（H） ion is coordinated with four oxygen atoms from three benzilie 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 Cd2O2 is formed by two dentate bridge coordination carboxyl oxygen atoms and two cadmium（Ⅱ） ions complex is also studied. CCDC： 716599. in the complex molecule.
