Abstract
X-ray analysis of [Cu . (5'-IMP) . H2O] has shown a structure containing polymeric chains of composition [Cu.5'-IMP]n in which the copper atom is directly bound to N(7) of the base and to three oxygen atoms of different phosphate groups. Whereas the coordination geometry in the analogous zinc complex resembles a distorted tetrahedrom, that in the copper complex is a distorted square plane with weak axial interactions.
摘要
对[Cu.(5'-IMP).H₂O]的X射线分析表明，其结构包含组成式为[Cu.5'-IMP]ₙ的聚合物链，其中铜原子直接与碱基的N(7)以及不同磷酸基团的三个氧原子相连。在类似的锌配合物中，配位几何形状类似一个扭曲的四面体，而在铜配合物中则是一个带有弱轴向相互作用的扭曲平面正方形。
