In the crystal structure of the title complex, {[Mn(C 11 H 14-NO 2) 2 (H 2 O) 3 ]Á2H 2 O} n , the two independent Mn II atoms are located on a centre of symmetry and coordinated by two 4-(diethylamino)benzoate (DEAB) anions and two water molecules in the basal plane while another water molecule bridges the Mn atoms in the apical directions, forming polymeric chains. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 11.33 (13) and 10.90 (9) and the benzene rings are oriented at a dihedral angle of 67.88 (6). The uncoordinated water molecules link the carboxylate groups and coordinated water molecules via O-HÁ Á ÁO hydrogen bonding. Weak C-HÁ Á Á interactions are also found in the crystal structure.

The title Mn II complex, [Mn(C 9 H 10 NO 2) 2 (H 2 O) 4 ]Á2H 2 O, is monomeric and centrosymmetric. It contains two 4-dimethylaminobenzoate ligands, four coordinated and two uncoordinated water molecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the distorted octahedral coordination is completed by the two water O atoms in the axial positions. In the crystal structure, intra-and intermolecular O-HÁ Á ÁO hydrogen bonds link the molecules into chains.

The asymmetric unit of the title complex, {[Mn(C 20 H 10 Br 2-N 3 O 5)(H 2 O)]Á(CH 3) 2 NCHO} n , consists of one Mn III ion, one (E)-5-bromo-N-[2-(5-bromo-2-oxidobenzylideneamino)-4nitrophenyl]-2-oxidobenzamidate ligand (Schiff base), one water molecule and an N,N-dimethylformamide molecule. The coordination geometry around the Mn III ion is a distorted octahedron, being surrounded by two O and two N atoms from the Schiff base, which are positioned in the equatorial plane. The water molecule and the O atom of the carbonyl group from the adjacent Mn III complex are situated at the axial positions, leading to a polymeric chain along the c axis. In the crystal, the complex and N,N-dimethylformamide molecules are connected via O-HÁ Á ÁO, C-HÁ Á ÁO and C-HÁ Á ÁBr hydrogen bonds, forming a three-dimensional network.

The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O} n , contains one Co(II) cation situated on a centre of inversion, one-half of a coordinating water mol-ecule, one 2,4,6-tri-methyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water mol-ecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxyl-ate group is twisted away from the attached benzene ring by 84.9 (2)°. The Co(II) atom is coordinated by two TMB anions and two water mol-ecules in the basal plane, while another water mol-ecule bridges the Co(II) atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the Co(II) cation is a slightly distorted octa-hedron. The coordinating and bridging water mol-ecules link to the carboxyl-ate groups via intra- and inter-molecular O-H⋯O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water mol-...

The two independent Mn II ions in the polymeric title compound, {[Mn 2 (C 6 H 2 N 2 O 4)(C 10 H 8 N 2)(H 2 O) 6 ]SO 4 Á3H 2 O}, exhibit distorted MnN 2 O 4 octahedral coordination geometries, with the pyrimidine-4,6-dicarboxylate (pmdc) ligand acting in the bis-chelating-(O,N:O 0 ,N 0) bridging mode and the 4,4 0-bipyridine (bpy) ligand in the-(N:N 0) bridging mode. The remaining coordination sites are occupied by O atoms of water molecules. As a consequence, cationic chains of [Mn 2 (-pmdc)(-4,4 0-bpy)(H 2 O) 6 ] 2+ are generated, which extend approximately along the a axis. Sulfate counter-anions and three uncoordinated water molecules complete the structure, which is stabilized by multiple O-HÁ Á ÁO hydrogen-bonding interactions between the structural units. metal-organic compounds Acta Cryst.

The asymmetric unit of the title compound, {[Zn 2 (C 10 H 2 O 8)-(H 2 O) 6 ]Á2H 2 O} n , contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxylate groups belonging to distinct halves of benzene-1,2,4,5-tetracarboxylate (tbec) tetraanionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octahedral knots. O-HÁ Á ÁO hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.

In the title complex, [C 14 H 12 MnN 2 O 4 ] n, the Mn(II) cation octahedrally coordinated by two N and two O atoms from two o-aminobenzoate ligands and two O atoms from another two o-aminobenzoate ligands. The carboxylate groups of two o-aminobenzoate anions coordinate to the Mn(II) cation in a monodentate manner, whereas the other two o-aminobenzoate anions chelate the Mn(II) cations through the O-atom of the carboxylate group and the N-atom of the amino group. This complex adopts the syn-anti carboxylate bridging mode with the conformation syn(eq)-anti(eq). The title complex is a two-dimensional coordination polymer based on an infinite MnAOACAOAMn chain. There is hydrogen bond interaction within the two dimensional network. The adjacent two-dimensional network is packed only by Van der Waals interactions.
