Abstract

The syntheses of a range of poly(methimazolyl)borate -ligated nitrosyl complexes of tungsten and molybdenum are reported, the characterization of which includes the crystal structure determinations of the compounds [W(NO)(CO) ₂{κ³-S,S′,S″-HB(mt)₃}], [W(NO)(CO)₂(PPh₃){κ²-S,S′-H ₂B(mt)₂}], and [Mo(NO-)(CO)₂{κ ³-H,S,S′-H₂B(mt)₂}] (mt = methimazoyl). The reaction of [W(NO)(CO)₃(PPh₃)₂]PF ₆ with Na[HB(mt)₃] and Na[H₂B(mt)₂] provides respectively [W(NO)(CO)₂{HB(mt)₃}] and [W(NO)(CO)₂(PPh₃)[κ²-S,S′-H ₂B(mt)₂}]. The complexes [M(NO)(CO)₂{HB(mt) ₃)] and [M(NO)(CO)₂{κ³-H,S,S′- H₂B(mt)₂}] (M = W, Mo) arise from the reactions of Na[M(CO)₃{H₂B(mt)₂}] with N-methyl-N- nitrosotoluenesulfonamide. The molybdenum complex [Mo(NO)(CO)₂ {HB(mt)₃}] is also obtained unexpectedly from the reaction of [Mo(η³-C₃H₅)(CO)₂{HB(mt) ₃}] with [NO]BF₄.
