Crystal Structure of (Cycloocta-1,5-diene)tris(hydrazine)hydrido-ruthenium(II) tetraphenylborate

摘要

The salt [RuH(COD)(H₂NNH₂)₃][BPh₄] (2) (COD = cycloocta-1,5-diene and BPh₄ = tetraphenylborate) was prepared by reacting the polymeric species [{Ru(COD)Cl₂}_x] (1; x 2) with hydrazine hydrate in refluxing ethanol. The obtained crystal was characterized by single-crystal X-ray analysis. The compound crystallizes in the monoclinic space group P2₁/n with unit-cell dimensions a = 9.7449(8)Å, b = 32.881(3)Å, c = 18.6962(16)Å, β = 99.571(10)°, V = 5907.3(9)Å3 and Z = 8. The ruthenium has a distorted octahedral geometry with two formula units comprising two cations and two anions in the asymmetric unit.
