In the title compound, [Ag(NH3)2]2[Pt(C2O4)2], the Ag atom is coordinated in an almost linear configuration by two N atoms from two ammine ligands. The Pt atom, located on an inversion centre, is tetracoordinated by four O atoms from two oxalate ions. The silver cations and platinum-centred anions are each stacked separately in a columnar fashion along the a axis. In the crystal structure, the cations and anions are further linked together through N—H...O hydrogen bonds, forming a three-dimensional structure.

The Mean

The title compound, C14H15N3O4, is nearly planar, the dihedral angle between the planes of the phenyl and pyrazolidine rings being 1.13 (7) Å, and that between the plane of the pyrazolidine ring and the mean plane of the side chain [C—N—C–C(=O)—O; r.m.s. deviation = 0.024 Å] being 2.52 (7)°. This is due in large part to the presence of the intramolecular N—H...O and C—H...O hydrogen bonds. In the crystal, pairwise N—H...O hydrogen bonds form inversion dimers, which are further associated into layers, lying very close to plane (-120),viapairwise C—H...O hydrogen bonds. The layers are then weakly connected through C—H...O hydrogen bonds, forming a three-dimensional structure.

In the title compound, [ZnBr3(C4H12N5)], the ZnIIcation is tetrahedrally coordinated by three bromide ions and the (N-{amino[(diaminomethylene)amino]methylene}-N-methylmethanaminium) cation that binds through the central N atom. The complex is of interest as a potential antidiabetic drug of the biguanide family. The crystal structure is stabilized by an extensive series of N—H...Br and C—H...Br hydrogen bonds, which combine to form a three-dimensional structure.
