Syntheses and Crystal Structures of Molybdenum-Sulfur Clusters Mo3S4 (dtp)3(o-CH3OC6H4COO)(Py) and Mo3S4 (dtp)3(p-HOC6H4COO)(DMF).EtOH

摘要

cqvip:The title compounds Mo3S4(dtp)3(o-CH3OC6H4COO)(Py) 1 and Mo3S(dtp)3(p-HOC6H4COO)(DMF)稥tOH 2 (dtp = diethyldithiophosphate) were synthesized by thereactions of Mo3S4(dtp)4(CH3CN) and Mo3S4(dtp)3(CH2ClCOO)(Py) with o-methoxylbenzoic acid and p-hydroxybenzoic acid, respectively. Their crystal structures were determined by X-ray diffraction analysis. The crystal data for compound 1: Mo3S10P3C25H42O9N, monoclinic P21/n, Mr = 1201.93, Z = 4, a = 14.164(1), b = 23.065(2), c = 14.732(1) ? = 109.677(1) ? V = 4532(1) ?, D= 1.762 gcm-3, = 1.428 mm-1, F (000) = 2408, R = 0.0739, wR = 0.1528 for 3552 observed reflections (I > 2); and for compound 2: Mo3S10P3C24H48O11N, triclinic P ? Mr = 1227.96, Z = 2, = 10.2098(3), b = 14.3333(4), c = 18.1711(5) ? = 94.694(1), = 102.166(1), = 110.665(1) , V = 2396.5(1)3, Dc = 1.638 gcm-3, = 1.350mm-1, F (000) = 1184, R = 0.0445, wR = 0.1281 for 6597 observed reflections (I > 2). Intermolecular S…S interactions are observed between the molecules of compound 1 while intramolecular O…HC and intermolecular S…HC hydrogen bondings are found in the crystal packing diagram of compound 2.
