Syntheses, characterization and crystal structures of [Cu(PCHO)2(2,2′-bipy)][BF4], [Cu2(PCHO)4(4,4′-bipy)][BF4]2 and [Cu2(PCHO)4(bptz)] [BF4]2 (PCHO=o-(diphenylphosphino)benzaldehyde and bptz=3,6-bis(2′-pyridyl)-1,2,4,5-tetrazine)
摘要:
Treatment of [Cu(PCHO)(2)(NCMe)][BF4] (1) (PCHO = o-(diphenylphosphino)benzaldehyde) with 2,2'-bipyridine produces the complex [Cu(PCHO)(2)(2,2'-bipy)][BF4](4), while the reactions of 1 with 4,4'-bipyridine and 3,6-bis(2'-pyridyl)-1,2,4,5-tetrazine (abbreviated as bptz) afford the dinuclear complexes [Cu-2(PCHO)(4)(4,4'-bipy)][BF4](2) (5) and [Cu-2(PCHO)(4)(bptz)][BF4](2) (6), respectively. The crystal structures of 4-6 have been determined by an X-ray diffraction study. The coordination about the Cu+ ion is trigonal for 5 and tetrahedral for 4 and 6, and there is no bonding between the aldehyde groups and the Cu+ ion in these compounds. (c) 2005 Elsevier B.V.
