Rhenium carbonyls containing pyridyl ligands incorporating an alkyne entity

Reactions of pyridyl ligands, 4,4′-dipyridylbutadiyne (DPB), 1,4-bis(4′-pyridylethynyl)benzene (BPEB), ferrocenyl-4-pyridylacetylene (FPA), 4-nitrophenyl-4′-pyridylacetylene (NPPA) and 4-aminophenyl-4′-pyridylacetylene (APPA), with Re(CO)5X (X = Cl.Br), cis-Re(CO)4(L)Cl (L = PPh3, P(OMe)3), and [Re(CO)3(2,2′-bipy)(MeCN)][PF6], provides fac-Re(CO)3(η1-DPB)2Cl (1), fac-Re(CO)3(PY)2Br (2, PY = FPA; 3, L = NPPA; 4, L = APPA), [fac-Re(CO)3(PPh3)Cl]2( μ-PY) (5, PY = BPEB; 6, PY = DPB), [fac-Re(CO)3(P(OMe)3)Cl]2( μ-DPB) (7), fac-Re(CO)3(PPh3)(PY)Cl (8, PY = NPPA; 9, PY = FPA), [fac-Re(CO)3(2,2′-bipy)(PY)][PF6] (10, PY = NPPA; 11, PY = APPA; 12, PY = FPA), and [{fac-Re(CO)3(2,2′-bipy)}2( μ-PY)][PF6]2 (13, PY = DPB; 14, PY = BPEB). The energy of the metal to pyridyl π * charge-transfer (MLCT) is investigated by electronic absorption spectra and cyclic voltammetry. X-ray structural analyses for 2 · CH2Cl2 and 12 · 2H2O were carried out. 2 · CH2Cl2: C12H28BrClN2O3P2Fe2Re; monoclinic; P21/n, Z=4; a =15.188(2), b= 15.100(2), c = 16.254(1) A; β = 102.22(1)°; R = 0.047; Rw = 0.040. 12 · 2H2O: C30H21F6N3O3PFeRe; monoclinic; P21/n, Z = 4; a = 19.022(4), b = 9.339(2), c = 21.111(3) A; β= 116.156(9)°; R = 0.043; Rw = 0.061.
