ABSTRACT: The Ni(II) atom in the title complex, [Ni(C(13)H(8)BrNOS)(C(18)H(15)P)], is coordinated by the N, O and S atoms of the dianionic tridentate ligand, and its square-planar geometry is completed by a phosphane P atom. The dihedral angle between the aromatic rings in the 4-bromo-2-[(2-sulfido-phen-yl)imino-meth-yl]phenolate ligand is 2.01?(14)°. The most prominent feature of the packing is the presence of supra-molecular chains aligned along the a axis, mediated by C-H?S inter-actions.
