Novel trinuclear and dinuclear nickel coordination compounds with a new pentadentate ligand. Crystal structures of [Ni3(bdnol)(EtOH)Cl5] and [Ni2(bdnol)Cl3]
Abstract
The pentadentate ligand 1,9-bis(3,5-dimethyl-1-pyrazolyl)-3,7-dithianonan-5-ol (Hbdnol)yields, with nickel chloride, the unique trinuclear compound [Ni3(bdnol)(EtOH)Cl5] with two [NiNSOCl3] and one [NiCl4OO′] distorted octahedral chromophores, and the dinuclear compound [Ni2(bdnol)CI3], with two [NiNSOCl2] distorted trigonal bipyramidal chromophores.
