Two complexes exhibiting monodentate metal co-ordination of a neutral guanidine have been synthesized and structurally characterised. Treatment of CoCl2 with 1,2,3-triphenylguanidine in tetrahydrofuran solution produced the tetrahedral complex [Co{(PhN)C(NHPh)2}2Cl2] 1 in which the guanidine ligands are co-ordinated through their imine nitrogen atoms alone. Similarly, treatment of the guanidine with Ag[SO3CF3] in toluene provided the linear complex [Ag{(PhN)C(NHPh)2}2][SO3CF3] 2 in which the triflate counter ion remains uncoordinated, but is hydrogen bonded to the guanidine hydrogen atoms. Both complexes have been characterised by X-ray crystallography.
