Tetranuclear dialkyl dithiophosphate complexes of molybdenum(V) with nitride ligands

The syntheses of the tetranuclear, ferromagnetic compounds [MoN(S2P(OR)2)2]4 (R = CH3 and C2H5) are described along with their unusual dissociative and chemical stabilities. The compound with R = CH3 crystallizes in the monoclinic space group A2/a with a = 18.632 (8) ?, b = 24.384 (12) ?, c = 12.600 (5) ?, β = 92.16 (1)°, and Z = 4 at -163°C. The structure was solved by direct methods (LSAM) using 3813 unique reflections with F > 2.33σ(F). Final residuals were R(F) = 0.082 and Rw(F) = 0.075. The chiral molecule contains a nearly square and planar [MoN]4 ring in which all bond distances are identical within experimental error. This portion of the structure contrasts markedly with the alternating triple and single bonds found in the [MoN]4 rings in the lattice of MoNCl3, and the differences in the structures are substantiated by the disparate values of ν(MoN). Explanations for the ferromagnetism are given in terms of a superexchange mechanism and molecular orbital theory.
