Synthesis, structure and spectroscopic properties of CuL(MeOH), H2L = ( E )- N 1 -(2-((2-aminocyclohexydiimino)(phenyl)methyl)-4-chlorophenyl)- N 2 -(2-benzyl-4-chlorophenyl)oxalamide.

A new kind of copper(II) complex, CuL(MeOH) (H2L?=?( E )- N 1 -(2-((2-aminocyclohexydiimino)(phenyl)methyl)-4-chlorophenyl)- N 2 -(2-benzyl-4-chlorophenyl)oxalamide) has been synthesized and its structure determined by single-crystal X-ray methods. Copper(II) ion is five-coordinate, bonding to four nitrogen atoms from H2L and one oxygen atom from MeOH. Hydrogen bonds in the crystal result in the formation of a one-dimensional structure. EPR spectra are discussed. Computer simulation gave g||?=?2.200, g??=?2.002. On the basis of the synthesis and the crystal structure, the mechanism of the metal template reaction involved in the formation of the complex was verified. [ABSTRACT FROM AUTHOR]
