摘 要： The title compound has been synthesized, the crystal structure of which has been detorminedby the single-crystal X-ray diffraction method. The crystal belongs to triclinic space group C-P1 with the unit cell parameters: a =9.535（2）A, b = 9.740（2）A, c = 15.795（4）A, α = 89.85（2）°, β = 91.80（2）°, γ = 99.37（1）°,ν = 1446.6A3, Ζ = 2. The structure is refined to R = 0.075, Rw = 0.074 for 1903 reflections. There are diverse bonding modes of molybdenum and sulfur in this eompound. The twosulfur atoms at the center bond to three molybdenum atoms from respective sides and formthe two apices of a trigonal bipyramid. Besides, there are S2-2 ligands and a polysulfur chaincomposed of three sulfur atoms. The coordination number for the three molybdenum atomsis seven. Their coordination polyhedra are somewhat distorted pentagonal bipyramid. Eachof the three NO ligands coordinated to molybdenum gives a linear group of Mo-N-O, whilethe fourth NO ligund bonded with a polysulfur chain forms a bent group of S-N
