Guanidinates as chelating anionic ligands for early, middle and late transition metals: syntheses and crystal structures of [Ti{η2-(NPh)2CNEt2}2Cl2], [Ru{η2-(NPh)2CNHPh}3] and [Pt{η2-(NPh)2CNHPh}2]
Guanidine anions as chelating ligands; syntheses and crystal structures of [Rh(η-C5Me5){η2-(NPh)2CNHPh}Cl] and [Ru(η-MeC6H4Pri-p)-{η2-(NPh)2CNHPh}Cl]
摘要:
Treatment of the chloro-bridged dimers [{Rh(eta-C(5)Me(5))Cl-2}(2)] and [{Ru(eta-MeC(6)H(4)Pr(i)-p)Cl-2}(2)] with 1,2,3-triphenylguanidine in toluene solution led to the formation of [Rh(eta-C(5)Me(5)){eta(2)-(NPh)(2)CNHPh}Cl] 1 and [Ru(eta-MeC(6)H(4)Pr(i)-p){eta(2)-(NPh)(2)CNHPh}Cl] 2 respectively. These represent the first examples of complexes containing guanidine anions as chelating ligands. Crystal structure analyses of bath complexes have been performed.
