Two copper complexes [Cu(TTA) 2 (4,4′‐azpy)] (1) and [Cu‐(TTA) 2 (3,3′‐azpy)] (2) (HTTA = 1,1,1‐trifluoro‐3‐(2‐thenoyl)‐acetone, 4,4′‐azpy = 4,4′‐azobispyridine, 3,3′‐azpy = 3,3′‐azobispyridine) were synthesized and characterized. The crystal structures were determined by X‐ray diffraction analysis. The crystal 1 belongs to triclinic with space group P 1 , a = 0.8515(2) nm, b = 0.9259(2) nm, c = 0.9468(2) nm, a = 66.126(9)°, β = 79.667(9)°, γ = 90.13(1)°, Z = 1, V = 0.6692(2) nm 3 , D c = 3.425 g/cm 3 , γ = 2.113 mm −1 , F (000) = 694, R 1 = 0.0594, wR 2 = 0.1499. The crystal 2 belongs to monoclinic with space group P2 1 /c, a = 1.0661(2) nm, b = 1.4296(3) ran, c = 1.0041(3) nm, β = 114.50(3)°, V = 1.3926(5) nm 3 , Z = 2, D c = 1.646 g/ cm 3 , μ = 1.015 mm −1 , F(000) = 694, R 1 , = 0.0535, wR 2 = 0.1113. In the crystals of complexes 1 and 2, the copper atoms have distorted octahedral symmetry. The two compounds possess very similar one‐dimensional linear chains linked through the rodlike 4,4′‐azpy ligands or 3,3′‐azpy ligands.
