| 摘 要： | <正> The title compound was obtained by the reaction of Mo3(μ3-O) (μ-S)3(dtp)4(H2O) with CH3COONa and pyridine. Mo3C19H38N1O9P3S9,Mr= 1093. 79, triclinic, space group P1, a = 12. 921(3) , b = 14. 260(3) , c= 12. 800(3)(?),α = 97. 54(2), β=116. 66(1), γ=100. 10(2) °, V = 2015, 2(8)(?)3, Z=2, Dc = 1. 80gcm-3, F(000) = 1092, final R = 0. 066 for 3444 observations, room temp. In the structure the three Mo atoms form an isosceles triangle capped by a μ3-O atom with three sides of 2. 589(2) , 2. 642(2), and 2. 627(2) (?) respectively, and the car-boxyl bridged Mo-Mo bond is the shortest one.
