A Trinuclear Cluster of Molybdenum(IV), Mo₃(μ₃-S)(μ₂-S)₃(HC₂O₄)₂(C₂O₄)(H₂O)₃

The three molybdenum centers in triaqua-1κO;2κO;3κO-bis[oxalato(1-)]-2κ²O,O′′; 3κ²O,O′′- oxalato(2-)-1κ²O,O′′-μ₃-thio-tri-μ-thio-1:2κ²S; 1:3κ²S; 2:3κ²S-triangulo-trimolybdenum diethanol solvate, [Mo₃S₄(C₂HO₄)₂(C₂O₄)(H₂O)₃].2C₂H₆O, form an equilateral triangle with an average Mo—Mo distance of 2.736 (4) Å. Each Mo atom is in a distorted octahedral environment made up of two O atoms of an oxalate ligand, one O atom of a water molecule, one capping-sulfur and two bridging-sulfur ligands. The structure is further stabilized by inter­molecular hydrogen bonding between the oxalate and water ligands.
