摘要
A novel complex [Cu(NITpPy)_2(H_2TCB)(H_2O)]·2H_2O (NITpPy =2-(pyrid-4'-yl)-4,4,5,5-tetramethyl-1,3-dioxoimidazoline; H_2TCB = 1,5-dicarboxybenzenecarboxylic-2,4-diacid) has been synthesized and characterized by X-ray crystallography analysis. Thecrystal structure consists of infinite chains of Cu(NITpPy)_2(H_2O) units linked by H_2TCB ligands.The complex crystallizes in triclinic system with space group P1. Crystal data: a = 1.0594(2) nm, b= 1.3830(3) nm, c = 1.5551(3) nm, α = 67.75(3)°, β = 89.83(3)°, γ = 70.54(3)°. The variablemagnetic susceptibility studies lead to magnetic coupling constant values of J_1 = -11.18 cm^(-1)(Cu-Rad) and J_2 = -4.06 cm^(-1) (Cu-Cu).
