摘要：
Ground-about: The ruthenium(II) complex [RuCl{N(CH2CH 2PtBu2)2}] (B) is obtained in high yield by the reaction of [RuCl2{HN(CH2CH2PtBu 2)2}] (A) with KOtBu. Complex B exhibits an unusual electronic low-spin (S=0) ground-state configuration. Comparison with Caulton's [RuCl{N(SiMe2CH2PtBu2)2}] (ground state: S=1) shows that the ground-state spin multiplicity in these complexes is controlled by the N→Ru π-donor strength. © 2010 Wiley-VCH Verlag GmbH & Co.
