M=1140.85, monoclinic, P21/c. a=12.748(2), b=14.320(2), c=23.118 (3)A,β=101.07(1)°, V=4141(2)A3, Z=4, Dc=1.830 g.cm-3. Final R=0.039 for 4160 reflections.The title compound is a rather irregular trinuclear molybdenum cluster having only two M-M bonds with two shorter Mo-Mo distances of 2.808(1), 2.839(1), and one longer Mo-Mo distance of 3.337(1)8. The existence of two Mo-Mo bonds is coincident with the electron counting for {Mo3} cluster core, and may be regarded as a result of the oxidation of a compound Mo3(μ3-S)(μ-S)2 (μ-L)[S2P(OEt)2]4(L’) (L’=neutral ligands)1 characterized by us previously.

The title compound is a rather irregular trinuclear molybdenum cluster having only two MM bonds with two shorter Mo-Mo distances of 2.808 (1), 2.839 ), and one longer Mo-Mo distance of 3.337 (1) 8. The existence of two Mo-Mo bonds is coincident with the electron counting for {Mo3} cluster core, and may be considered as a result of the oxidation of a compound Mo3 (μ3-S) (μ-S) 2 (μ-L) [S2P (OEt) 2] 4 (L ’
