Syntheses and characterization of trans-[NiL_2(NCS)_2][L = 2-(aminomethyl) pyridine], trans-[NiL_2(NSC)_2][L' = 2-(2-aminoethyl)pyridine] and trans-[NiL±_2(NSC)_2] [L' = 2-(2methylaminoethyl)pyridine] complexes: X-ray single crystal structure of trans-[NiL__2(NSC)_2] [L' = 2-(2-aminoethyl)pyridine]

摘要

[NiL_2(NCS)_2] (1) [L= 2-(aminomethyl)pyridine], [NiL_2(NCS)_2](2)[(L')= 2-(2-aminoethyl)pyridine and [NiL_±_2(NCS)_2](3)[L" = 2-(2-methylaminoethyl)pyridine] have been synthesized from solution. All the complexes possess trans geometry as is evident from solid state UV-Vis spectral study and X-ray single crystal structure analysis of complex 2 unambiguously proves trans geometry of the species.
