The title compound was prepared by adding a solution of glycin (0.075 g, 1 mmol) in 5 ml H2O to a solution of (Et4N)2Mo2S2O2(edt)2 (0.366 g, 0.5 mmol) in 5 ml DMF. After stirring about 10 min, the solution was filtered. Orange block crystals of the title compound were obtained by slow evaporation of the orange filtrate for several weeks. (Et4N)2Mo2S2O2(edt)2 was synthesized by the literature (Lin et al.,1998).
All H atoms were positioned geometrically and treated as riding atoms (including free rotation about the C—NH3+ bond), with C—H = 0.97 Å and N—H = 0.89—0.90 Å, with Uiso(H) = 1.2 Ueq(C, N) (1.5 for —NH3+ groups). Rint value of 0.086 and R of 0.0869 indicate a low structure quality.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Dimolybdenum complexes containing [Mo2O2(µ-S)2] have attracted many chemists' attention, not only because the [Mo2O2(µ-S)2] unit has special stability but also because it may be employed as a starting material to react with many transition metals. Some [Mo2O2(µ-S)2] structural compounds based on amino-acid have been isolated and structurally characterized (Spivack & Dori, 1975; Li et al., 2005). The crystal structure of our new neutral dimolybdenum glycinato complex is similar to the compound [Mo2O4(C2H4NO2)2(C2H5NO2)] (Liu et al., 2000).
The title structure consists of the neutral Mo2O2(µ-S)2(C2H5NO2)(C2H4NO2)2 (Fig. 1). In the structure, the two molybdenum atoms are not crystallographically equivalent, which are linked by two µ2-S ligand and one glycine (+H3NCH2COO-) ligand in an O:O'-bidentate mode. Each MoV atom is also bonded to one terminal oxygen atom and chelated by one N,O-glycine (NH2CH2COO-) ligand, resulting in a distorted octahedral coordination. The Mo···Mo separation is 2.788 (2) Å, which is shorter than the Mo···Mo distance (2.848 (1) Å) in the histidinato complex (Spivack & Dori, 1975). The Mo—S, Mo—N, Mo—O and Mo?O bond lengths are 2.304 (5)—2.336 (4) Å, 2.195 (12)—2.225 (11) Å, 2.091 (11)—2.328 (9) Å and 1.668 (11)—1.696 (10) Å, respectively.
A three-dimensional network is constructed by six classic intermolecular N—H···O hydrogen bonds (Table 1 and Fig. 2).
