title: Syntheses and structural characterization of rhenium-bis-hydrazinopyrimidine core complexes with thiolate and Schiff base coligands.
abstract: The reaction of perrhenate with 2-hydrazinopyrimidine in MeOH-HCl yields [ReCl(3)(eta(1)-NNC(4)H(3)N(2)H)(eta(2)-HNNC(4)H(3)N(2))] (1). The analogous reaction with Na(2)MoO(4) yields [MoCl(3)(eta(1)-NNC(4)H(3)N(2)H)(eta(2)-HNNHC(4)H(3)N(2))] (1a). The reaction of 1 with pyrimidine-2-thiol and triethylamine produces [Re(eta(1)-C(4)H(3)N(2)S)(eta(2)-C(4)H(3)N(2)S)(eta(1)-NNC(4)H(3)N(2))(eta(2)-HNNC(4)H(3)N(2))] (2), while reaction of 1 with the Schiff base HSC(6)H(4)N=C(H)C(6)H(4)OH provides [Re(eta(3)-SC(6)H(4)N=C(H)C(6)H(4)O)(eta(1)-NNC(4)H(3)N(2))(eta(2)-C(6)H(4)O)(eta(1)-NNC(5)H(4)N)(eta(2)-HNNC(5)H(4)N)] (4), was also synthesized by reacting [ReCl(3)(eta(1)-NNC(5)H(4)NH)(eta(2)-HNNC(5)H(4)N)] with HSC(6)H(4)N=C(H)C(6)H(4)OH. The crystal structures of 1-4 have been determined.
