Bis(glycinato-kappa2N,O)dinitrosylmolybdenum(0) and bis(2-aminoethanethiolato-kappa2N,S)dinitrosylmolybdenum(0) acetonitrile monosolvate.

The title compounds, [Mo(C(2)H(4)NO(2))(2)(NO)(2)], (I), and [Mo(C(2)H(6)NS)(2)(NO)(2)].CH(3)CN, (II), contain distorted octahedral complexes in which the monoanionic N,S- and N,O-bidentate ligands coordinate the molybdenum centres in different modes. The anionic O atoms of the glycinate ligands in (I) are coordinated trans to the nitrosyl ligands and the amine N atoms are located trans to each other, whereas in (II) the anionic S atoms are coordinated trans to each other and the amine N atoms are located trans to the nitrosyl ligands.
