{2-[2-(Ethylamino)ethyliminomethyl]-5-methoxyphenolato}thiocyanatonickel(II)

Abstract

Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.008 Å; R factor = 0.052; wR factor = 0.127; data-to-parameter ratio = 13.4.In the title mononuclear nickel(II) complex, [Ni(C 12 H 17 -N 2 O 2 )(NCS)], the metal atom is four-coordinated in a tetrahedrally distorted square-planar geometry by the phenolate O atom, the imine N atom and the amine N atom of the Schiff base ligand and by the N atom of a thiocyanate ligand. In the crystal structure, centrosymmetrically related molecules are linked into dimers through intermolecular N-HÁ Á ÁO hydrogen bonds. These dimers are further connected by intermolecular C-HÁ Á ÁS hydrogen bonds, forming chains running parallel to [101]. Related literature ExperimentalCrystal data [Ni(C 12

Two New Isomeric Di-μ-oxo Bis[oxovanadium(V)] Complexes Containing Schiff Base Ligands

“…In addition, the presence of vanadium haloperoxidases has particularly stimulated the search for the structural and functional models based on vanadium complexes [11,12]. Recently, some dioxovanadium(V) complexes with Schiff base ligands have been reported [13][14][15], and few iron complexes derived from 2-[(2-ethylaminoethylimino)methyl]-6-methoxyphenolate (L 1 ) [16][17][18], and few copper and nickel complexes derived from 2-[(2-ethylaminoethylimino)methyl]-5-methoxyphenolate (L 2 ) [19][20][21] are reported, but the vanadium complexes with tridentate Schiff base ligands derived from N-ethylethane-1,2-diamine have never been reported. Here, we report the synthesis and structures of two new isomeric dioxovanadium(V) complexes, [VO 2 L 1 ] 2 (1) and [VO 2 L 2 ] 2 (2).…”
