摘要:
The title compound, tris(diethyl dithiophosphato)1k(2)S,S';2k(2)S,S';3k(2)S,S' -mu-o-nitrobenzoato-2kO:3kO'-pyridine- 1kN-mu(3)-thio-tri-mu-thio-1:2k(2)S;1:3k(2)S;2:3k(2)S-triangulo-trimolybdenum(3 Mo-Mo), [Mo3S4(C7H4N- O-4)(C4H10PS2)(3) (C5H5N)], was synthesized in a mixed solvent of acetonitrile and ethanol by a ligand-substitution reaction in which o-nitrobenzoic acid replaces the bridging diethyl dithiophosphate (DTP) ligand. The average Mo-Mo bond distance is 2.731(2) Angstrom. The substitution of o-nitrobenzoate for DTP shortens the Mo-Mo bond that it bridges to 2.693 (1) Angstrom.
