Abstract
The reaction of methylphosphine sulfide, MeP(S)(3,5-Me2Pz)2, 1, with anhydrous CuCl2 affords a tetranuclear copper cluster[Cu2Cl2(3,5-Me2Pz)3(MePO3)]2, 2, and a dinuclear compound Cu2Cl4(3,5-Me2Pz)4, 3. This reaction involves a metal-assisted desulfurization along with concomitant hydrolysis of P-N bonds. The X-ray structures of 1-3 have been determined, and the crystal parameters for these are the following. 1: space group = C2/c, a = 15.2552(1) Å, b = 8.7364(2) Å, c = 21.4490(3)Å, β = 93.349(1)° , V = 2853.74(8) Å3, and Z = 8. 2: space group = P21/n, a = 12.5964(4) Å, b = 15.7773(4) Å, c = 13.9781(4) Å, β= 116.6280(10)° , V = 2483.32(12) Å3, and Z = 2. 3: space group = P21/c, a = 8.7137(8) Å, b = 13.5493(14) Å, c = 11.8847(12) Å, β = 106.179(2)° , V = 1347.6(2) Å3, and Z = 2. The structure of 2 shows that it comprises two dinuclear copper cores bridged together by two tripodal methylphosphinate, MePO3, ligands. 2 is weakly antiferromagnetically coupled, as revealed by variable temperature magnetic susceptibility measurements.
