Two complexes CuLCl(H2O) 1 and Ni(L)2 2 (HL = 2-carboxy-1,10-phenanthroline) have been synthesized and characterized by single-crystal X-ray crystallography. The structure of 1 has a monoclinic space group P21/n with a = 7.985(2), b = 16.067(3), c = 9.694(2) , β = 98.189(30)°, V = 1231.0(4) 3, Z = 4, Dc = 1.836 g/cm3, μ =1.998 mm-1, F(000) = 684, the final R = 0.0301 and wR = 0.0810. The structure of 2 (C26H14N4NiO10) adopts an orthorhombic system, space group Pbca with a = 9.410(2), b = 23.2410(5), c = 23.8680(5) , V = 5219.9(18) 3, Z = 8, Mr = 601.12, Dc = 1.530 g/cm3, μ = 0.809 mm-1, F(000) = 2448, the final R = 0.0448 and wR = 0.1427. The Cu center of complex 1 exhibits a square pyramidal coordination environment with one oxygen and two nitrogen atoms from deprotonated 2-carboxy-1,10-phenanthroline, one oxygen atom from water and one chloride ion. The Ni center of complex 2 assumes a distorted octahedral coordination geometry consisting of two oxygen atoms and four nitrogen atoms of two deprotonated 2-carboxy-1,10-phenanthroline molecules. Supramolecular assembly has been found via noncovalent bonds, such as hydrogen bonds and π-π stacking interactions.
