Four new Schiff base complexes of first row transition metals viz. mononuclear [CoL3] (1), [NiL2] (2), [CuL2] (3) and binuclear [Cu2L2(NCS)2] (4) where HL = 2-[((2-(thiophene-2-yl)ethyl)imino)methyl]phenol, a bidentate Schiff base derived from 2-thiopheneethylamine and salicylaldehyde have been prepared. Characterization has been made with different physicochemical studies including single crystal X-ray diffraction. Structural studies indicate that the mononuclear complex 1 has a distorted octahedral geometry while 2 and 3 are square planar. On the other hand, 4 is a phenoxo-bridged binuclear species in which each copper(II) ion adopts a distorted square pyramidal geometry. In the solid states, intermolecular C–H⋯π or π⋯π interactions are operative in 2 and 4.

Abstract
Four new Schiff base complexes of first row transition metals viz. mononuclear [CoL3] (1), [NiL2] (2), [CuL2] (3) and binuclear [Cu2L2(NCS)2] (4) where HL = 2-[((2-(thiophene-2-yl)ethyl)imino)methyl]phenol, a bidentate Schiff base derived from 2-thiopheneethylamine and salicylaldehyde have been prepared. Characterization has been made with different physicochemical studies including single crystal X-ray diffraction. Structural studies indicate that the mononuclear complex 1 has a distorted octahedral geometry while 2 and 3 are square planar. On the other hand, 4 is a phenoxo-bridged binuclear species in which each copper(II) ion adopts a distorted square pyramidal geometry. In the solid states, intermolecular C–H⋯π or π⋯π interactions are operative in 2 and 4.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
