In the title compound, [Cd(C8H4O4)(C17H10N4O)] n, the CdII atom is six-coordinated by four O atoms from three different benzene-1,3-dicarboxyl­ate (C8H4O42−; 1,3-BDC) ligands and two N atoms from the bidentate 2-furan-2-yl-1 H-imidazo[4,5- f]-1,10-phenanthroline (C17H10N4O) ligand in a distorted octa­hedral geometry. The CdII atoms are bridged by the 1,3-BDC ligands to form a double-chain structure. Neighbouring double chains inter­act through π–π inter­actions, resulting in a two-dimensional network.

In the title compound, bis­(μ-pyridine-2,5-dicarboxyl­ato)bis­[aqua­(pyrazino[2,3- f][1,10]phenanthroline)manganese(II)] dihydrate, [Mn2(C7H3NO4)2(C14H8N4)2(H2O)2]·2H2O, each MnII atom is six-coordinated by three N atoms from one bidentate pyrazino[2,3- f][1,10]phenanthroline and one monodentate pyridine-2,5-dicarboxyl­ate ligand, and three O atoms from two monodentate pyridine-2,5-dicarboxyl­ate ligands and one water mol­ecule. The two MnII atoms are bridged by two pyridine-2,5-dicarboxyl­ate ligands, forming a centrosymmetric dinuclear molecule. Neighboring mol­ecules inter­act through π–π contacts, leading to a one-dimensional supra­molecular structure, and O—H⋯O hydrogen bonds complete the structure. [ABSTRACT FROM AUTHOR]

In the title compound, [Cu(C19H11N4)2(H2O)]·2H2O or [Cu( L)2(H2O)]·2H2O, where H L is 2-phenyl-1 H-1,3,7,8,-tetra­azacyclo­penta­[ l]phenanthrene, the CuII atom is five-coord­inated by four N atoms from two L− ligands and one O atom from one water mol­ecule. A three-dimensional supra­molecular structure is formed through π–π and hydrogen-bonding inter­actions. [ABSTRACT FROM AUTHOR]

The title complex, [Cu2(C16H10NO2)4(H2O)2], has a centrosymmetric wheel-shaped dinuclear structure in which two symmetry-related CuII centers are bridged by four carboxyl­ate groups of distinct 2-phenylquinoline-4-carboxyl­ate (phqc) ligands, the Cu—Cu separation being 2.6507 (12) Å. Each CuII center is five-coordinated by four O atoms of carboxyl­ate groups in the basal plane and one O atom of a water mol­ecule in the apical position. In addition, the dinuclear mol­ecules are linked by inter­molecular O—H⋯N hydrogen bonds to form a one-dimensional supramolecular chain. [ABSTRACT FROM AUTHOR]

In the title compound, {[Mn(C7H3NO4)(C10H8N2)(H2O)]·H2O} n, the Mn(II) atom has a distorted fac-MnN3O3 octahedral coordination geometry, defined by one N, N′-chelating bipyridine molecule, one N-bonded pyridine-3,4-dicarboxylate (pdb) anion, two monodentate O-bonded pdb anions and one water molecule. Adjacent MnII ions are bridged by pairs of pdb ligands to form distinctive squares, which are further linked by other pdb ligands to result in a layered coordination polymer exhibiting a wave-like structure. Hydrogen bonds involving both the coordinated and uncoordinated water molecules help to consolidate the structure. [ABSTRACT FROM AUTHOR]
