The title compound [Cu 2 (phen) 2 (C 9 H 14 O 4 ) 2 ] · 6 H 2 O was prepared by the reaction of CuCl 2 · 2 H 2 O, 1,10‐phenanthroline (phen), azelaic acid and Na 2 CO 3 in a CH 3 OH/H 2 O solution. The crystal structure (monoclinic, C 2/ c (no. 15), a = 22.346(3), b = 11.862(1), c = 17.989(3) Å, β = 91.71(1)°, Z = 4, R = 0.0473, w R 2 = 0.1344 for 4279 observed reflections) consists of centrosymmetric dinuclear [Cu 2 (phen) 2 (C 9 H 14 O 4 ) 2 ] complexes and hydrogen bonded H 2 O molecules. The Cu atom is square‐planar coordinated by the two N atoms of the chelating phen ligand and two O atoms of different bidentate bridging azelaate groups with d(Cu–N) = 2.053, 2.122(2) Å and d(Cu–O) = 1.948(2), 2.031(2) Å. Two azelaate anions bridge two common Cu atoms via the terminal O atoms (d(C–O) = 1.29(2) Å; d(C–C) = 1.550(4)–1.583(4) Å). Phen ligands of adjacent complexes cover each other at distances of about 3.62 Å, indicating π‐π stacking interaction, by which the complexes are linked to 1 D bands.
