文摘

A new complex, [Cu(BTZ)(DMF)Cl]₂ [BTZ = 2-(2-hydroxyphenyl)benzothiazolate, DMF = N,N-dimethylformamide], was synthesized and characterized by X-ray crystallography, elemental analysis, IR spectrum, and TG−DTG. The results show that the complex crystallizes in a monoclinic space group P21/c; a = 10.478(3) Å, b = 8.993(3) Å, c = 18.482(6) Å; β = 105.697(5)°; V = 1676.59 ų; and Z = 4. The structure of the complex is dimeric [Cu(BTZ)(DMF)Cl]₂ with two isotropic Cu²⁺ ion centers having five-coordinate geometry. The constant-volume combustion energy of the complex, Δ_cU, was determined as being (−17689.56 ± 6.77) kJ·mol⁻¹ by a precise rotating-bomb calorimeter (RBC-type II). The standard molar enthalpy of combustion, Δ_cH_m^θ, and the standard molar enthalpy of formation, Δ_fH_m^θ, were calculated at 298.15 K as being (−17706.91 ± 6.77) kJ·mol⁻¹ and (−738.67 ± 7.96) kJ·mol⁻¹, respectively.
