N2 - The syntheses, structures, and properties of mononuclear oxo- and sulfidomolybdenum(IV) complexes with hy-drotris(3,5-dimethyl-l-pyrazolyl)borate, HB(Me2pz)3~, and dithiocarbamate ligands are described. The reactions of MoO-(S2CNR2)2(R = Me, Et, n-Pr, «-Bu) with K{HB(Me2pz)3(in refluxing toluene yield the green, diamagnetic, air-stable complexes| HB(Me2pz)3]MoO(S2CNR2). The complex jHB(Me2pz)3)MoO(S2CNEt2) crystallizes in the monoclinic space group P2Jc with a = 8.303 (2) Å, b = 21.710 (4) Å, c = 14.475 (3) Å, β = 100.75 (2)°, Z - 4. The molybdenum atom is in a distorted octahedral coordination environment composed of/aotridentate HB(Me2pz)3“, terminal oxo (Mo=0 = 1.669 (3) Å), and bidentate S2CNEt2” ligands. The reaction of these oxo complexes with boron sulfide in dichloromethane yields the gold-yellow, diamagnetic sulfido analogues| HB(Me2pz)3}MoS(S2CNR2). The compound {HB(Me2pz)3}MoS(S2CNEt2)•CH2Cl2crystallizes in the orthorhombic space group P212121with a = 7.967 (3) Å, b = 14.314 (5) Å, c = 26.15 (1) Å, Z = 4. The coordination geometry is similar to that of the oxo analogue, with Mo=S = 2.129 (2) Å.
