The synthesis and crystal structure of a novel cubane-like complex of the MoAgS series: {MoAg 3S 3Cl}(PPh 3) 3O

Abstract

A novel MoAgS cubane-like complex, {MoAg 3S 3Cl}(PPh 3) 3O, has been synthesized from AgCl, PPh 3 and Mo 2O 2S(S 2) 4 2− in appropriate conditions, and its X-ray crystal structure determined. The complex comprises one cubane-like cluster core {MoAg 3S 3Cl} 2+, three PPh 3 ligands attached to each silver atom and one terminal oxo ligand attached to the molybdenum atom [1.67(1) Å]. The mean distance of the molybdenum and silver atoms is 2.980(2) Å, which is too long to effectively bond. The bond lengths of the three AgCl bonds are in the same range and average to 2.810(4) Å.
