A novel use of an oxime molecule as supramolecular tecton. Synthesis of a Pt (II) 2D network

To test the hypothesis that we could use the 4-pyridiniumcarboxaldehyde oxime (4-HoxpyH) coordinated through the oxime N atom to organize Pt(II) compounds via charge-assisted [ > N-H] +center dot center dot center dot[Cl2Pt]- hydrogen bonds, we synthesized and determined the crystal structure of the compound [PtCl3(4-HoxpyH)], 1. The structure of 1 shows that the ligand HoxpyH coordinates through the nitrogen atom of the oxime group and forms the expected H-bonds. In the crystal, six molecules interact through hydrogen bonds and O center dot center dot center dot Cl interactions, forming rings that extend into two-dimensional structures. These 2D structures are stacked on top of each other through Pt center dot center dot center dot pyH and Pt-Cl center dot center dot center dot pyH interactions, without interpenetrating or forming channels.
