The heterometallic title complex, [Cr(2)Mn(2)(C(5)H(11)NO(2))(2)(C(5)H(12)NO(2))(2)(NCS)(4)]·4C(3)H(7)NO, was prepared using manganese powder, Reineckes salt, ammonium thio-cyanate and a non-aqueous solution of N-methyl-diethano-lamine in air. The centrosymmetric mol-ecular structure of the complex is based on a tetra-nuclear {Mn(2)Cr(2)(μ-O)(6)} core. The tetra-nuclear complex mol-ecule and the two uncoordinated dimethyl-formamide mol-ecules are linked by O-H⋯O hydrogen bonds, while the two other mol-ecules of dimethyl-formamide do not participate in hydrogen bonding.

In the title compound, {[Cu(C24H15N2O4)2(H2O)2]·4C3H7NO} n , the Cu(II) ion, lying on an inversion center, is six-coordinated by two N atoms from two 4-[6-(4-carb-oxy-phen-yl)-4,4'-bipyridin-2-yl]benzoate (L) ligands, two deprotonated carboxyl-ate O atoms from two other symmetry-related L ligands and two water mol-ecules in a slightly distorted octa-hedral geometry. The Cu(II) atoms are linked by the bridging ligands into a layer parallel to (101).

In the title compound, [Cu(2)Cl(4)(C(12)H(8)N(2)O(4))(2)]·4C(3)H(7)NO, which contains a chloride-bridged centrosymmetric Cu(II) dimer, the Cu(II) atom is in a distorted square-pyramidal 4 + 1 coordination geometry defined by the N atoms of the chelating 2,2'-bipyridine ligand, a terminal chloride and two bridging chloride ligands. Of the two independent dimethyl-formamide mol-ecules, one is hydrogen bonded to a single -COOH group, while one links two adjacent -COOH groups via a strong accepted O-H⋯O and a weak donated C(O)-H⋯O hydrogen bond. Two of these last mol-ecules and the two -COOH groups form a centrosymmetric hydrogen-bonded ring in which the CH=O and the -COOH groups by disorder adopt two alternate orientations in a 0.

In the title complex, {[Mn(3)(C(9)H(4)O(6))(2)(C(9)H(5)O(6))(2)(C(3)H(7)NO)(4)(H(2)O)(2)]·4C(3)H(7)NO}(n), one Mn(II) ion sits on an inversion center, and is six-coordinated by four O atoms from four anions (monoanionic and dianionic) derived from benzene-1,3,5-tricarboxylic acid and by two dimethyl-formamide (DMF) mol-ecules in a slightly distorted octa-hedral geometry. The other Mn(II) ion is six-coordinated by four O atoms from four monoanionic and dianionic ligands, one DMF mol-ecule and one water mol-ecule in a distorted octa-hedral geometry. The monoanionic and dianionic ligands bridge the Mn(II) ions, resulting in the formation of a layered structure parallel to (111) in which all of the carboxyl-ate groups of the anionic ligands coordinate the Mn(II) ions in a monodentate manner.
