In the title compound, [Zn(C4H2O4)(C14H8N4)]n, the ZnII atom is five-coordinate and exhibits a distorted trigonal-bipyramidal coordination. The ZnII atoms are further bridged by fumarate ligands, forming a two-dimensional network parallel to the ab plane. [ABSTRACT FROM AUTHOR]

In the title complex, [Cu2(C8H4O4)2(C6H6N2O)4]·3H2O, the CuII atom exhibits distorted trigonal–bipyramidal geometry and is coordinated by two N atoms of two isonicotinamide (inta) ligands and three O atoms of three isophthalate (ipt) ligands. C—H⋯O and N—H⋯O hydrogen bonds, as well as π–π stacking inter­actions, are observed between. [ABSTRACT FROM AUTHOR]

In the title compound, {[Cu(C14H8O5)(C14H8N4)]·H2O} n, the CuII atom adopts a distorted cis-CuN2O2 square-planar coordination geometry. 4,4′-Oxydibenzoate ( L) ligands link the CuII atoms, generating a helical chain. Neighbouring chains are linked through π–π interactions between pyrazino[2,3- f][1,10]phenanthroline ligands with a centroid–centroid distance of ca 3.44 Å, resulting in a two-dimensional supramolecular structure. The structure is completed by O—H...O hydrogen bonds. [ABSTRACT FROM AUTHOR]

The Co atom in the title compound, [Co(C6H5N2O4)2(H2O)2], is located on an inversion centre and exhibits a distorted octahedral geometry. It is trans coordinated by two N, O-bidentate 5-carboxy-2-methyl-1 H-imidazole-4-carboxylate monoanionic ligands with two water molecules in the axial positions. Each ligand is stabilized by a strong, almost symmetrical, hydrogen bond. Intermolecular N—H...O hydrogen bonds link the molecules into layers, which are further linked into a three-dimensional supramolecular framework through O—H...O hydrogen-bonding interactions involving the water molecules.

In the title compound, [Zn(1,4-BDC)(L)]n, where 1,4-BDC is the benzene-1,4-dicarboxylate dianion, C7H3O4N2-, and L is dipyrido[3,2-a:2',3'-c]-phenazine, C18H10N4, each ZnII atom is five-coordinated by two N atoms (from one dipyrido[3,2-a:2',3'-c]phenazine ligand) and three O atoms (from two monodentate benzene-1,4-dicarboxylate ligands and one water molecule). The ZnII atoms are bridged by benzene-1,4-dicarboxylate ligands, forming a one-dimensional chain structure. Neighboring one-dimensional chains interact through π-π contacts, leading to a two-dimensional supramolecular structure, and O—H…O hydrogen bonds complete the structure. [ABSTRACT FROM AUTHOR]

In the title compound, [Fe2(SO4)2(C18H10N4)2(H2O)4]·H2O, the FeII atoms are octa­hedrally coordinated by two N atoms from one bidentate dipyrido[3,2-a:2′,3′-c]phenazine (dppz) ligand, two O atoms belonging to two SO42− anions and two water O atoms. The two crystallographically independent dinuclear complex mol­ecules are both generated by inversion symmetry with the sulfate ions acting as bridges. Neighbouring dinuclear complexes inter­act via O—H⋯O hydrogen bonds, leading to a chain structure. [ABSTRACT FROM AUTHOR]

In the title mol­ecule, C14H11NO3S, the benzoisothiazole ring system and the benzyl group form a dihedral angle of 87.7 (9)°. The crystal structure is stabilized by weak inter­molecular C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]
