The coordination chemistry of alkaline earth metal hydrazides has been investigated, and the synthesis and crystal structures of monomeric magnesium bis[ N ‐phenyl‐ N′ , N′ ‐bis(trimethylsilyl)hydrazide] ( 1 ) and dimeric magnesium bis[ N , N ‐dimethyl‐ N′ ‐(trimethylsilyl)hydrazide] ( 2 ) are presented. An unusual coordination sphere of the magnesium atom was observed in the first structurally characterized monomer magnesium hydrazide 1 , a highly reactive compound with side‐on coordinated hydrazide ligands forming a bent butterfly‐type structure. The Mg−N distances range from 1.92 to 2.45 Å and intramolecular C−H ··· Mg interactions in the range 2.42 to 2.63 Å are observed. This structural motif is unprecedented in the coordination chemistry of magnesium hydrazides. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
