| Abstract: A Cu(Ⅱ) complex (2) of 2-[(2-bromo-phenylimino)-methyl]-4-chloro-phenol (1) generated from 5-chloro-salicylaldehyde and o-bromoaniline was synthesized and characterized by elemental analysis and single crystal X-ray diffraction. Compound 1 is in the orthorhombic system, space group Pbca with a=0.710 19(12) nm, b=1.308 2(2) nm, c=2.533 3(5) nm, Mr=310.57, V=2.353 6(7) nm3, Dc=1.753 g·cm-3, F(000)=1 232, μ=3.700 mm-1, Z=8, R=0.025 0 and wR2=0.055 5. Compound 2 belongs to the monoclinic system, space group P21/c with a=0.956 8(2) nm, b=1.085 3(3) nm, c=1.204 7(3) nm, β=105.965(7)°, V=1.202 8(6) nm3, Mr=682.67, Dc=1.885 g·cm-3, Z=2, μ=4.481 mm-1, F(000)=670, R=0.045 0 and wR2=0.122 5. Compound 1 is stabilized by intermolecular C-H…N and intra-molecular C-H…O hydrogen bonds, C-H…Cl and π…π interaction and further linked into a 2D layer structure. But compound 2 is connected by halogen…halogen and C-H…π hydrogen bond to form a 3D network. CCDC: 803365, 1; 803366, 2. | |||||
