| Abstract: 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) nm3, 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. |
