✦ Synopsis

The µ 4 -oxo tetranuclear magnesium compound [Mg 4 (µ 4oxo)(µ-tz) 6 ] 1 (tz = 3,5-iPr 2 -1,2,4-triazolato) with six η 1 -η 1bridging triazolato ligands was prepared in a one-step reaction between MgBr 2 and tzK. The solid state structure was determined by X-ray diffraction analysis showing the tetrahedral arrangement of the Mg 4 O core. The reaction of MgBr 2 with pzK and pzH gave [Mg(pz) 2 (pzH) 2 ] 2 (pz = 3,5-tBu 2 -pyrazolato), which contains hydrogen bonds between two differ-[
