Popis: | A series of polypyridyl ruthenium(II) complexes containing monodentate pyridyl- and cyano-substituted acetylenes have been prepared. Complexes of the type Ru(tpy)(bpy)L{sup 2+} (where tpy = 2,2{prime}:6{prime}:2{double_prime}-terpyridine (C{sub 15}H{sub 11}N{sub 3}), bpy = 2,2{prime}-bipyridine (C{sub 10}H{sub 8}N{sub 2}), and L = pyridine (py) (C{sub 5}H{sub 5}N), pyridylacetylene (PA) (C{sub 7}H{sub 5}N), phenylpyridylacetylene (PPA) (C{sub 10}H{sub 9}N), dipyridylacetylene (DPA) (C{sub 12}H{sub 8}N{sub 2}), CH{sub 3}CN, cyanoacetylene (CA) (C{sub 3}HN), and cyanophenylacetylene (CPA) (C{sub 9}H{sub 5}N)) have been prepared, and their synthesis and characterization are reported herein. The complexes [Ru(tpy)(bpy)(PPA)](PF{sub 6}){sub 2}{center_dot}(CH{sub 3}){sub 2}CO, [Ru(tpy)(bpy)(PA)](PF{sub 6}){sub 2}{center_dot}(CH{sub 3}){sub 2}CO, and [Ru(tpy)(bpy)(CH{sub 3}CN)](PF{sub 6}){sub 2} have been crystallized and the crystal structures determined. [Ru(tpy)(bpy)(CH{sub 3}CN)](PF{sub 6}){sub 2} crystallizes in the monoclinic P2{sub 1}/c space group. [Ru(tpy)(bpy)(PA)](PF{sub 6}){sub 2}{center_dot}(CH{sub 3}){sub 2}CO crystallizes in the triclinic P{bar 1} space group. [Ru(tpy)(bpy)(PPA)](PF{sub 6}){sub 2}{center_dot}(CH{sub 3}){sub 2}CO crystallizes in the triclinic P{bar 1} space group. The inclusion of the functionalized acetylene groups makes these complexes possible precursors to metal-coordinated polyacetylenes. |
