Metal complexes of N-substituted guanidines are well known in the field of inorganic, organometallic chemistry, catalysis and materials chemistry. Factors that determine coordination modes of this class of N-donor ligands determine nuclearity of the resulting complexes. Herein we report a straight forward high yield syntheses and complete characterisation of two dinuclear cycloplatinated guanidinate(2−) complexes 3 and 4 wherein the ligand revealed an unprecedented tridentate μ₂-κ²(C,N):κ¹N coordination mode as revealed by single crystal X-ray diffraction. A plausible mechanism for the formation of 3 and 4 is outlined.
