B. E. Kucera, M. M. Olmstead, R. S. Tanke and S. M. Kauzlarich

Abstract: The compound [MgCl₂(C₁₈H₁₅OP)₂] was inadvertantly crystallized during a reaction involving magnesium germanide. It is isostructural to the Mn, Co, Cu and Zn analogs. Since four-coordinate Mg is rare, its structure is reported here. The Mg atom lies on a twofold axis and is surrounded by two O atoms and two Cl atoms in a distorted tetrahedral coordination geometry.
