The centrosymmetric binuclear complex, [Zn 2 (C 8 H 7 O 2 ) 4 (C 7 H 7 NO) 2 ], has been synthesized and characterized by FT-IR and NMR methods. The obtained Zn(II) metal complex has been also characterized by a single crystal X-ray diffraction study. Crystal data for C 46 H 42 N 2 O 10 Zn 2 : Monoclinic, Space group P2 1 /c (no. 14), a = 10.4827(3) A, b = 8.6141(2) A, c = 24.7582(6) A, β = 101.066(1) °, V = 2194.07(10) A 3 , Z = 4, D calc = 1.383 g/cm 3 , 22545 reflections measured (3.96° ≤ 2Θ ≤ 52.74°), 4465 unique ( R int = 0.0388, R sigma = 0.0333) which were used in all calculations. The final R 1 was 0.0489 (I ≥ 2s(I)) and wR 2 was 0.1533 (all data). The four nearest oxygen atoms around each zinc ion form a distorted square-planar arrangement, and the distorted square-pyramidal coordination is completed by the nitrogen atom of the 1-(pyridin-4-yl)ethanone compound.
