Synthesis and characterization of new addition compounds of bis(2-hydroxyaryloximato) nickel(II) with α-diimines

Crystallographic Determination of Three Ni-α-Hydroxyoxime-Carboxylic Acid Synergist Complexes

“…[24,25] If the coordination sphere is instead expanded by the addition of a bidentate, cis-chelating ligand, a more significant structural rearrangement is required. Such structures have been observed upon addition of an aliphatic [26] or aromatic [27] diamine, with the two salicylaldoxime ligands arranged in a "folded" cis conformation. Despite this structural rearrangement, intra-molecular hydroxyoxime-hydroxyoxime hydrogen bonding persists.…”

Bis(2-hydroxyiminomethyl-6-methoxyphenolato-κ2O1,N)nickel(II)

“…For the structure of bis(salicylaldoximato)nickel, see: Srivastava et al (1967). The title compound is expected to form complexes with nitrogen-donor ligands as bis(salicylaldoxinato)nickel forms such adducts; see, for example, Hultgren et al (2001); Lalia-Kantouri et al (1999); Ma et al (2007a,b).…”
