The reaction of the molybdenum–dinitrosyl complexes with PPh 3, using 2-pyrimidinethiolate (pymt) or 2-pyridinethiolate (pyt) as a thiolate ligand, was found to produce a dinuclear complex [{(ON)MoL 2} 2(μ-OH) 2] ( 1) (L = pymt or pyt) and Ph 3PO. In addition, the first reported example of a mixed valence molybdenum–nitrosyl tetranuclear complex, [Ph 3POH] 2[{(ON)Mo(pymt) 2} 2(μ-MoO 4) 2] ( 2), was produced by the reaction of 1(pymt) with Ph 3PO. This is the first published nitrosyl complex containing both tetraoxomolybdate and thiolato ligands. The molybdenum and bridging oxygen atoms formed a novel eight-membered ring with a central porous structure.
