A series of new complex salts of the type [R]2[MC14] where R =[Ph-C=n-N-Ph N=N-Ph],M = Mn2+, Co2+, Ni2+, Cu2+ and Zn2+ wereprepared and characterized by elemental analysis, molar conductance, IR and UVNis is spec...A series of new complex salts of the type [R]2[MC14] where R =[Ph-C=n-N-Ph N=N-Ph],M = Mn2+, Co2+, Ni2+, Cu2+ and Zn2+ wereprepared and characterized by elemental analysis, molar conductance, IR and UVNis is spectral studies and magnetic measurements.The crystal structure of[Ph-C=n-N-Ph N=N-Ph]2[CuCl4] was determined by single crystal X-ray crystallography. The structure consisted of anion part and a 2,3,5-(triphenyl) tetrazolium cation as counter ions. The copper complex has a distorted tetrahedral geometry, the CI(1)-Cu-CI(2) [124.33 (2°)] and Cl(3)-Cu-Cl(4) [131.03 (2°)] angles are significantly larger than the ideal tetrahedral. The [CuCI4] anion and its counter ions are connected through a hydrogen bonds between C1 of the dianion and hetero aromatic rings by Cl-π, π-π and C-H … π, interactions.展开更多
