A novel asymmetric dinuclear carboxylate-bridged Zn(Ⅱ) complex, \[Zn 2 (ad am) 4 (phen)\]·H 2 O(adam -=adamantanecarboxylato group, phen=1,10-phenanthroline), has been synthesized by reaction of adamantanecarbo ...A novel asymmetric dinuclear carboxylate-bridged Zn(Ⅱ) complex, \[Zn 2 (ad am) 4 (phen)\]·H 2 O(adam -=adamantanecarboxylato group, phen=1,10-phenanthroline), has been synthesized by reaction of adamantanecarbo xylic acid with Zn(CH 3 COO) 2 ·2H 2 O in 1,10-phenanthroline. The crystal structu re results as elucidated by XRD indicates that it is an adamantanecarboxylat o Zn(Ⅱ) complex, in which the two Zn(Ⅱ) ions are t riply-bridged by three adamantanecarboxylato groups, with a distance of 0 325 9(1) nm between each other. In the dinuclear zinc complex, one Zn(Ⅱ) ion ha s a distorted tetrahedral geometry and the other has a distorted octahedral geom etry.展开更多
