metal-organic compounds
The title PtIV complex, [PtCl4(C16H28N4O6)] or trans-[PtCl4{NH=C(Et)ON=C(Me)C(=O)OEt}2], possesses a crystallographically imposed centre of symmetry. The coordination environment of the metal centre is a slightly distorted octahedron. An intramolecular N—HN hydrogen bond between the imine H atom and the oxime N atom stabilizes the E configuration of the imine groups.

The title compound, [Pt(C3H3N2)Cl3(C3H4N2)2], has mirror symmetry. The PtIV atom has a slightly distorted octahedral geometry, with three facial Cl atoms and three N atoms, the latter from one pyrazolate (pz) and two pyrazole (pzH) ligands. There is an intramolecular N—HNH—N hydrogen-bonding system, with NN distances of 2.747 (7) Å.
