The geometry of the Cd atom in the polymeric title complex, {[Cd(SO4)(C2H5N5)2]·H2O}n, is six-coordinate distorted octahedral, defined by two 0-atom donors derived from two sulfate dianions and four N atoms from four different 3,5- diamino-1,2,4-triazole ligands. The sulfate dianions interact with CdII atoms, forming infinite strands running in the c-axis direction. The three-dimensional supramolecular structure is stabilized by N—H…O and O—H…N interactions. The two independent water molecules lie on different twofold axes and interact with the network through hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title compound, [Mn(C7H3NO4)(C12H8N2)(H2O)2]·H2O, the MnII atom is surrounded by one 1,10-phenanthroline (phen) ligand, one pyridine-2,5-dicarboxyl­ate (pydc) dianion and two water mol­ecules in a distorted octa­hedral MnN3O3 coordination. Hydrogen bonding between neighbouring mol­ecules leads to a two-dimensional network. [ABSTRACT FROM AUTHOR]

The title complex, [Ni(C3H2O4)(C12H8N2)(H2O)2]·3H2O, displays a distorted octa­hedral NiN2O4 coordination geometry, formed by a malonate dianion, a 1,10-phenanthroline ligand and two trans water mol­ecules. The Ni atom and one O atom, the latter from a solvent water mol­ecule, are located on twofold axes of symmetry. The crystal structure is stabilized by extensive O—H⋯O hydrogen-bonding inter­actions.

Mol­ecules of the title compound, C23H24N4O, are linked into chains by O—H⋯N hydrogen bonds and C—H⋯π inter­actions. Aromatic π–π stacking inter­actions exist between chains. [ABSTRACT FROM AUTHOR]

In the title compound, C24H34O8, a strong intra­molecular O—H⋯O hydrogen bond is formed between the OH substituent of salicyaldehyde and the aldehyde O atom. [ABSTRACT FROM AUTHOR]

Theare are two independent mol­ecules in the asymmetric unit of the title compound, C24H34O8. The crystal packing is mainly determined by weak inter­molecular C—H⋯O hydrogen bonds and van der Waals inter­actions. [ABSTRACT FROM AUTHOR]
