Abstract
A series of heteronuclear-Pt(II) complexes containing ferrocenylethynyl units linked directly (Pt–CCFc) or through a phosphorous atom (Pt-PPh2CCFc) to the platinum center is reported. The reaction of derivative [cis-Pt(RF)2(PPh2CCFc)2] (RF = C6F5) 1 with the solvate complex [cis-Pt(RF)2(thf)2] leads to the formation of an asymmetrical heteronuclear diplatinum complex [{Pt(RF)2(μ-1κP:2η2-PPh2CCFc)2}Pt(RF)2] 9 having the “cis-Pt(RF)2” fragment coordinated to the triple bonds of both ferrocenylethynylphosphine units, while treatment of [cis-Pt(CCFc)2(PPh2CCR)2] (R = Fc 5a, Ph 5b, tBu 5c) with the same solvate [cis-Pt(RF)2(thf)2], affords double ferrocenylacetylide-bridged diplatinum systems [{Pt(PPh2CCR)2(μ-η1:η2-CCFc)2}Pt(RF)2] 10. The solid-state structures of [cis/trans-Pt(RF)2(PPh2CCFc)2] 1/2, [cis-Pt(RF)2(PPh2CCFc)(tht)] 3 (tht = CFc)2}Pt(RF)2] 9 and [{Pt(PPh2CCtBu)2(μ-η1:η2-CCFc)2}Pt(RF)2] 10c have been determined by CFc or CCFc CFc 9) or (η1:η2-CCFc 10)
