Metal complexes synthesis and properties

Self-assembling of the tris-chelated [Cr(bpm)(ox)2]- complex with Na+ in aqueous solution leads to the remarkable bimetallic honeycomb layered compound of formula [NaICrIII(bpm)(ox)2]·5H2O (2) (bpm and ox are 2,2'-bipyrimidine and oxalate, respectively), where both bpm and ox act as bis-chelating ligands (structure depicted). Replacement of Na+ by AsPh4+ leads to the ionic salt of formula AsPh4[Cr(bpm)(ox)2]·H2O (1).
