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
