摘要
由简单小分子配体和金属镉离子形成的配合物通过氢键可以构筑具有高级有序结构的分子聚集体,这些分子聚集体在制备具有磁性、生物活性、光学性质和催化性能等新材料方面有着潜在的应用前景。由于Cd(Ⅱ)金属配合物具有很好的荧光性能及抗菌等性质而受到人们关注。近年来.对于以羧酸为配体与金属离子配位形成的配合物有大量报道.
A seven-coordinate dimmer has been synthesized with 5-oxo-4-oxa-tricyclo[4.2.1.0]nonane-9-carboxylic acid and 1,10-phenanthroline. The crystal structure was determined by single-crystal X-ray structural analysis. The crystal belongs to a monoclinic system, space group P21/n, with a=1.552 08(12) nm, b=1.065 52(8) nm, c=1.626 57 (12) nm,β=100.100 (10)°, V=2.648 3 (3) nm^3, Dc=1.643 g·cm^-3, Z=2, F (000)=1 328, Final GooF=1.026, R1= 0.026 2, wR2=0.059 2. The crystal structure shows that the cadmium ion is coordinated with five oxygen atoms and two nitrogen atoms, forming a distorted capped octahedral coordination geometry. There exist two types of coordinated 5-oxo-4-oxa-tricyclo [4.2.1.0]nonane-9-carboxylic acid anions: the tridentate-chelating-bridging ones and the bidentate-chelating ones. The Cd(Ⅱ).--Cd(Ⅱ) distance is 0.373 7 nm. The luminescence property of the complex is also studied. CCDC: 7299551.
