Notes. Malonato(ethylenediamine) complexes of chromium(III): the structure of di-µ-hydroxo-bis[(ethylenediamine)malonatochromium(III)]

Abstract

In the preparation of new malonatoethylenediamine complexes of chromium(III) for kinetic investigations the bridged dimer [{Cr(en)(mal)(OH)}₂] has been isolated. The preparation of two other complexes and the crystal structure of the dimer are reported, and the relevance of the structure is discussed with respect to both kinetic and magnetic coupling studies with chromium(III).
