A refinement of the structure of bisglycinocopper(II) monohydrate, Cu(NH2CH2COO)2.H2O

Abstract

The crystal structure of bisglycino-copper(II) monohydrate, which was originally determined by Tomita & Nitta in 1961, has been refined by three-dimensional least-squares methods. The molecular geometry of this cis complex is essentially the same as reported earlier, but the standard deviations of the distances have been reduced to a third of their previous values. The groups C~-CO-O of both glycine molecules are highly planar, the entire chelate part of the complex only approximately so. The environment of the water molecule is trigonal. An error analysis of the reflection data is presented.
