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

T. Yonemura

Abstract: In the title compound, [Mo(C₅H₄NS)₃(NO)]·2H₂O, the Mo atom is coordinated by a nitrosyl ligand and three monoanionic N,S-bidentate ligands in a distorted MoN₄S₃ 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.
