Poly(methimazolyl)borato nitrosyl complexes of molybdenum and tungsten

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){k(3)-S,S',S''-HB(mt)(3)}], [W(NO)(CO)(2)(PPh3){k(2)-S,S'-H2B(mt)(2)}], and [Mo(NO-)(CO)(2) {k(3)-H,S,S'-H2B(mt)(2)}] (mt = methimazoyl). The reaction of [W(NO)(CO)(3)(PPh3)(2)]PF6 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){k(2_) S,S'-H2B(mt)(2)}]. The complexes [M(NO)(CO)(2){HB(mt)(3)}] and [M(NO)(CO)(2){k(3)-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(eta(3)-C3H5)(CO)(2){HB(mt)(3)}] with [NO]BF4.
