Structure and spectroscopic properties of bis(N-cyclohexyl-3-methoxy-salicylideneiminato)copper(II)

摘要: The structure of the title complex (2) has been determined from three-dimensional X-ray counter data. material crystallizes in monoclinic space group P21/c with two monomeric units a cell dimensions a= 11.793(5), b= 18.043(14), c= 6.484(3)A, and β= 67.12(2)°. Least-squares refincment 1 190 independent data led to final values R R′ 0.047 0.046, respectively. are crystallographically constrained be square planar. green solid yields reddish solutions various solvents. Electronic e.s.r. spectroscopic support presence pseudo-tetrahedrally distorted species solutions. Spectroscopic for planar compared pseudo-tetrahedral bis(N-cyclohexylsalicylidene-iminato)copper(II), (1). Structure-spectra correlations applicable state cannot necessarily straightforwardly applied solution species.
