The title compound, [Cu(2)(OH)(2)(C(6)H(16)N(2))(2)(H(2)O)](BF(4))(2), consists of dinuclear centrosymmetric [Cu(2)(OH)(2)(tmen)(2)(H(2)O)](2+) complex cations (tmen = N,N,N',N'-tetra-methyl-ethane-1,2-diamine) and tetra-fluoridoborate anions. In the cation, the Cu(II) atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH(-) anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water mol-ecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598 (9):0.269 (6):0.134 (8). The crystal packing is governed by ionic forces as well as by O-H⋯F hydrogen bonds.

In the title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(58)H(52)N(2)P(4))](BF(4))(2), the dinuclear cation lies on an inversion centre. The Cu(I) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and two P atoms from an N,N,N',N'-tetra-kis-[(diphenyl-phos-phan-yl)meth-yl]benzene-1,4-diamine ligand in a distorted tetra-hedral geometry. In the crystal, inter-molecular C-H⋯F hydrogen bonds link the ions into layers parallel to [[Formula: see text]01].

The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water molecules. In this 1:2 complex (one metal for two organic ligands) each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for chelate binding.

The bidentate 1,3,4-thia-diazole ligand substituted by two 2-pyridyl rings (denoted L) has been found to produce the new monomeric title complex, [Co(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The thia-diazole and pyridyl rings surrounding the Co atom are almost coplanar [dihedral angle = 4.35 (7)°].

In the title copper(II) salt, [Cu(C(6)H(6)N(4))(2)(C(2)H(6)OS)(2)](BF(4))(2), the Jahn-Teller distorted octa-hedral coordination sphere of copper is formed from four 2,2'-bi-1H-imidazole N atoms and two dimethyl sulfoxide O atoms. The Cu atom lies on a center of inversion. N-H⋯O and N-H⋯F hydrogen bonds give rise to a one-dimensional structure.
