The compound (I) was synthesized by bubbling H2S gas into a 20 ml aqueous solution of Na2MoO4.2H2O (4.84 g, 20 mmol). The solids of Na2S2O4 (0.469 g, 2.7 mmol) and 2-aminoethanethiol (2 g, 26 mmol) were added to the red solution with stirring for about 4 h at 358 K. After cooling to room temperature, the solution was filtered and the residue was dissolved in 10 ml DMF. Orange prism crystals of (I) were obtained by slow evaporation of the orange solution for several weeks.
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.97 and N—H = 0.90 Å and Uiso(H) = 1.2Ueq(C, N).
Molybdenum chalcogenides have been extensively studied due to their applications in modelling of molybdoenzymes in biological systems. During the course of exploring polynuclear molybdenum clusters, dinuclear molybdenum complexes are always considered as excellent starting materials. Many compounds containing a [Mo2O2(µ-S)2] structural unit have been isolated and structurally characterized (Bunzey et al., 1977; Drew & Kay, 1971; Dulebohn et al., 1991; Howlader et al., 1984; Li et al., 2005; Llusar et al., 2005; Müller et al., 1982; Spivack & Dori,1970). Herein, we report the crystal structure of a new dinuclear molybdenum complex, (I).
In the structure of (I) (Fig. 1), the two Mo atoms are not crystallographically equivalent, which are linked by two µ-S atoms. Each Mo atom is chelated by one 2-aminoethanethiolate (aet) ligand in the equatorial plane. The two aet ligands are in a trans form. Each Mo atom is also bonded to one terminal O atom in the axial position, resulting in a five-coordinated square-pyramidal coordination geometry. In virtue of weak intermolecular N—H···O and N—H···S hydrogen bonds, a three-dimensional hydrogen-bonding network is constructed (Fig. 2).

Molybdenum chalcogenides have been extensively studied due to their applications in modelling of molybdoenzymes in biological systems. During the course of exploring polynuclear molybdenum clusters, dinuclear molybdenum complexes are always considered as excellent starting materials. Many compounds containing a [Mo2O2(µ-S)2] structural unit have been isolated and structurally characterized (Bunzey et al., 1977; Drew & Kay, 1971; Dulebohn et al., 1991; Howlader et al., 1984; Li et al., 2005; Llusar et al., 2005; Müller et al., 1982; Spivack & Dori,1970). Herein, we report the crystal structure of a new dinuclear molybdenum complex, (I).
In the structure of (I) (Fig. 1), the two Mo atoms are not crystallographically equivalent, which are linked by two µ-S atoms. Each Mo atom is chelated by one 2-aminoethanethiolate (aet) ligand in the equatorial plane. The two aet ligands are in a trans form. Each Mo atom is also bonded to one terminal O atom in the axial position, resulting in a five-coordinated square-pyramidal coordination geometry. In virtue of weak intermolecular N—H···O and N—H···S hydrogen bonds, a three-dimensional hydrogen-bonding network is constructed (Fig. 2).
