Nitro­syltris(pyridine-2-thiol­ato-κ(2) N,S)molybdenum(II) dihydrate

In the title compound, [Mo(C(5)H(4)NS)(3)(NO)]·2H(2)O, the Mo atom is coordinated by a nitrosyl ligand and three monoanionic N,S-bidentate ligands in a distorted MoN(4)S(3) penta­gonal-bipyramidal mol­ecular geometry. The pyridine N atom of one pyridine-2-thiol­ate (pyt) ligand is coordinated to the Mo atom in the trans position relative to the NO ligand [N(pyt)—Mo—N(NO) = 170.62 (19)°]. The compound has C (s) symmetry, with a mirror plane that includes one pyt ring and the NO group. The S—Mo—N(NO) and N(pyt)—Mo—N(NO) angles [97.24 (12) and 91.87 (8)°, respectively] are large relative to the ideal angles of 90°. In the crystal, the mol­ecules pack in a zigzag arrangement. The cavities between the mol­ecules are occupied by disordered water mol­ecules of crystallization.
