A new Schiff base 2-[(3-bromo-phenylimino)methyl]phenol (HL) (1), derived from condensation of salicylaldehyde with m-bromoaniline, and its copper(II) complex (2) [Cu2L4], have been prepared and characterized by single crystal X-ray diffraction. Schiff base is in the monoclinic system, space group P21 with a = 3.928(14) Å, b = 10.590(4) Å, c = 13.212(5) Å, b = 97.360(4)°, Mr = 276.13, V = 5451(3) Å3, Dc = 1.682 g/cm3, Z = 2, μ = 3.745 mm-1, F(000) = 276, R = 0.0326, wR = 0.0455. Complex belongs to the monoclinic system, space group P21/n with a = 13.970(9) Å, b = 11.891(7) Å, c = 15.232(9) Å, b = 114.876(9)°, Mr = 1227.55, V = 2296(2) Å3, Dc = 1.776 g/cm3, Z = 2, μ = 4.460 mm-1, F(000) = 1212, R = 0.1801, wR = 0.2158. 1 is stabilized by intermolecular C-H…O and p…p interaction and further linked into a 2D layer structure. But compound 2 is connected by halogen…halogen and C-H…p hydrogen bond and Cu…H interaction to form a 3D network.
