Synthesis and structural characterization of bis-cyclometalated complexes [M(ptpy)2(S2COCH3)] (M=Rh, Ir; ptpy=2-(p-tolyl)pyridinato)
摘要:
The synthesis of the bis-cyclometalated complexes [M(ptpy)(2)(S2COCH3)] (M = Rh, 1; M = Ir, 2; ptpy = 2-(p-tolyl)pyridinato) from [{M(mu-Cl)(ptpy)(2)}(2)], carbon disulfide and sodium methanolate as the base are described. Compound 1 and 2, respectively, were crystallized from dichloromethane/methanol and the molecular structures of both complexes were confirmed by single-crystal X-ray diffraction studies (both monoclinic, P2(1)/c). The emission spectrum of 1 exhibited the new compound as a red-emitting complex. (C) 2012 Elsevier B. V. All rights reserved.
