A novel gadolinium（Ⅲ） complex with N-（2-propionic acid）-salicyloyl hydrazone （C10H10N2O4, H3L） and 1,10-phenanthroline （C12H8N2, phen） was prepared and characterized.

The crystal structure of [Gd（H2L）（HL）- （H2O）3]2·phen·4H2O was determined by X-ray single crystal diffractometry. The crystal complex crystallizes in the triclinic system with space group P-1. There are two 9-coordinated structure units in every complex molecule, in which Gd（Ⅲ） is coordinated by two tridentate ligands （H2L and HL forms） and three water molecules and both the structural units take a distorted monocapped square antiprism. There is a free 1,10-phenanthroline connecting with coordinated water by hydrogen bonds in the crystal. The bioactivity tests indicate that the complex is an inhibitor against three bacteria.展开更多
