The P2CuN2 coordination geometry is pseudo-tetrahedral, with P—Cu—P and N—Cu—N angles of 116.02 (6) and 101.5 (2)°, respectively.The title compound, [Cu(C DOI: 10.1107/S1600536808008386/ng2437Isup2.hkl            Structure factors: contains datablocks I.

The Ru—N distances are in the range 2.036 (2)–2.084 (2) Å with the exception of the central Ru—N bond from the terpyridyl ligand, which is shorter [1.9503 (19) Å], as expected. The pendant dimethoxyphenyl substituent is not coplanar with the terpyridyl unit; the dihedral angle between the central pyridyl ring and the benzene ring is 46.72 (11)°. The anion is disordered equally over two positions around an F—P—F bond axis.In the title compound, [RuCl(C DOI: 10.1107/S1600536809032589/is2438Isup2.hkl            Structure factors: contains datablocks I.

The dihedral angles between the planes of the substituted Cp ring and the major and minor components of the disordered ring are 0.8 (3) and 3.4 (6)°, respectively. The crystal packing is stabilized by intermolecular O—H⋯O hydrogen bonds, forming zigzag chains running parallel to the a axis.In the structure of the title compound, [Fe(C DOI: 10.1107/S1600536809023575/rz2334Isup2.hkl            Structure factors: contains datablocks I.

The unique MnII ion is located on a crystallographic inversion center and is coordinated by two –NH2 and two –SO3 groups from four 4-aminobenzenesulfonate ligands and by two water molecules in the axial positions, forming a slightly distorted octahedral coordination environment. The 4-aminobenzenesulfonate anions behave as μ2-bridging ligands to produce a two-dimensional structure. In the crystal structure, intermolecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds link the layers into a three-dimensional network.The title compound, {[Mn(NH DOI: 10.1107/S1600536808025579/lh2671Isup2.hkl            Structure factors: contains datablocks I.

The dihedral angles between the pyridine rings and the mean planes of the 1,10-phenanthroline ring system in each of the 1--2-pyridone (PP) ligands is 24.51 (10)° for the tridendate PP ligand and 73.55 (6)° for the bidentate PP ligand. Within the molecule there is a weak π–π interaction between the pyridine ring of the bidentate ligand and the 1,10-phenanthroline ring system of the tridendate ligand with a centroid–centroid distance of 3.6383 (19) Å.In the title mononuclear complex, [Zn(ClO DOI: 10.1107/S1600536809025355/lh2853Isup2.hkl            Structure factors: contains datablocks I.

The asymmetric unit contains one CuII ion, one 3,5-dinitro-2-oxidobenzoate ligand and a 3-hydroxypyridine ligand. Coordination by one N atom and three O atoms from two different 3,5-dinitro-2-oxidobenzoate ligands and a 3-hydroxypyridine ligand creates a square-planar CuII center, which is augmented by a less tightly bonded fifth phenol O atom to form a square-pyramidal five-coordinate complex with an essentially planar base. The double-stranded chains are stabilized by intrachain π–π interactions [the centroid-to-centroid distance between adjacent aromatic rings is 3.719 (7) Å], and further linked through O—H⋯O hydrogen bonds, forming a three-dimensional supramolecular network.A new coordination polymer, [Cu(C DOI: 10.1107/S1600536808009392/zl2099Isup2.hkl            Structure factors: contains datablocks I.
