摘要：
Attempts to prepare complexes of the type [Zn(tripod)L](x+), where L is a uninegative anion, yielded only bis(tripod)zinc(II) complexes. The crystal structures of two of these bis(tripod)zinc(II) complexes, bis(tris(pyrazolyl)methane)zinc(II) nitrate (I) and bis(tris(pyridine)methanol)zinc(II) nitrate-4-hydrate (II) are described The geometries about the zinc atoms are close to octahedral and average Zn-N distances are 2.136 and 2.148 Angstrom for I and II, respectively. There are no significant interligand interactions which might mitigate against the formation of the bis(tripod)zinc(II) complexes. The reasons for the preference for these complexes over those sought are discussed.
