The ligand benzyl N'-(2-methoxybenzoyl)hydrazinecarbodithioate (H(2)mbhcd) (1), having a NOS donor sequence, formed a series of complexes [M(Hmbhcd)(2)](n) M = Mn(II), Co(II) and Ni(II) (2, 5 and 6)}, [Mn(Hmbhcd)(2)(o-phen)] center dot DMSO (3) and [Mn-2(Hmbhcd)(2)(2,2'-bpy)(2)(mu-OAc)(2)] (4). The complexes 3 and 4 have been obtained as single crystals, containing o-phen/2,2'-bpy as coligands. The compounds 2, 5 and 6 have been characterized with the aid of elemental analyses, IR, UV-Vis, magnetic susceptibility and mass spectrometry. Compound 3 crystallized in the triclinic system with the space group P (1) over bar while 4 crystallized in the monoclinic system with the space group P2(1)/c. The (N,O) donor sites of the uninegative bidentate ligand chelates the Mn(II) center to form a five-membered MnOCN2 ring in both complexes 3 and 4. (C) 2009 Elsevier Ltd. All rights reserved.
