Abstract

The reaction of perrhenate with 2-hydrazinopyrimidine in MeOH-HCl yields [ReCl₃(η¹-NNC₄ H₃N₂H)(η²-HNNC₄ H₃N₂)] (1). The analogous reaction with Na₂MoO₄ yields [MoCl₃(η¹-NNC₄ H₃N₂H)(η²-HNNHC₄H₃ N₂)] (1a). The reaction of 1 with pyrimidine-2-thiol and triethylamine produces [Re(η¹-C₄H₃ N₂S)(η²-C₄H₃ N₂S)(η¹-NNC₄H₃N₂) (η²-HNNC₄H₃N₂)] (2), while reaction of 1 with the Schiff base HSC₆H₄N=C(H)C₆H₄OH provides [Re(η³-SC₆H₄ N=C(H)C₆H₄O)(η¹-NNC₄ H₃N₂)(η²-HNNC₄H₃ N₂)]·0.6CH₂Cl₂ (3·0.6CH₂Cl₂). The analogous hydrazinopyridine complex of the Schiff base, [Re(η³-SC₆H₄ N=C(H)C₆H₄O)(η¹-NNC₅ H₄N)(η²-HNN C₅H₄N)] (4), was also synthesized by reacting [ReCl₃(η¹-NNC₅H₄ NH)(η²-HNNC₅H₄N)] with HSC₆H₄N=C(H)C₆H₄OH. The crystal structures of 1-4 have been determined.
