Crystal structure of cis-diamminebis(nitrito-κN)platinum(II).

Abstract

Single crystals of cis-[Pt(NO2)2(NH3)2] were grown from a hypersaturated plating electrolyte. The divalent Pt(II) center adopts a square-planar geometry coordinated by four nitrogen atoms from two ammine and two monodentate nitrite ligands in a cis arrangement. The crystal packing features close-packed molecular stacks running along [001]. Nine crystallographically distinct intermolecular N-H⋯O hydrogen bonds generate an hxl-type network in which every molecule functions as an eight-connected node; four of these bonds link complexes within the same [001]-parallel column. Unlike the previously characterized trans isomer, no intramolecular hydrogen bonding is observed in this structure.
