Ethanol(nitrato)[tris(4-cyano-3-phenyl-1H-pyrazol-1-yl)hydroborato]nickel(II)
Keyword(s):
The synthesis and structure is reported of TpPh,4CNNi(NO3)(EtOH) or [Ni(C30H19BN9)(NO3)(C2H6O)], the first half-sandwich complex of a cyanoscorpionate ligand. The pseudooctahedral coordination sphere of the NiII ion is comprised of a tridentate tris(4-cyano-3-phenylpyrazolyl)borate ligand, a bidentate nitrate ligand and a neutral ethanol ligand. The phenyl substituents on the TpPh,4CN ligand are relatively parallel to the planes of the ethanol and nitrate ligands. An intermolecular hydrogen-bonding interaction is evident between the ethanol OH group and the pyrazole CN substituent. The ethanol ligand was modeled with a 0.572 (13)/0.428 (13) disorder of the methyl C atom.
