Structural evidence for a new type of π-arene complex containing poly-(1-pyrazolyl)borate ligands and carbocyclic π-acceptor ligands. X-Ray analysis of [tetrakis-(1-pyrazolyl)borato](h6–benzene)ruthenium(II) hexafluorophosphate
Abstract
Crystal structure analysis of {(C6H6)Ru[B(pz)4]}+PF6– where B(pz)4 represents the tetrakis-(1-pyrazolyl)borate group, has shown that the B(pz)4 ligand is tridentate and the benzene ring is hexahapto.
