| Abstract: | A series of copper(II) complexes, Cu(L1)(NCS)] (I), CuBr(L2)] (II), and CuCl(L3)] (III), where L1, L2, and L3 are 2,4-dibromo-6-(pyridin-2-ylmethylimino)methyl]phenolate, 4-chloro-2-(pyridin-2-ylmethylimino)methyl]phenolate, and 1-(pyridin-2-ylmethylimino)methyl]-naphthalen-2-ol, respectively, were prepared. The complexes were characterized by elemental analysis, IR spectra, and single crystal X-ray determination. The crystals of the three complexes crystalize in the monoclinic space group P21/n. For I, a = 8.127(2), b = 13.077(3), c = 14.967(3) Å, β = 91.975(2)°, V = 1589.8(6) Å3, Z = 4. For II, a = 7.736(2), b = 10.613(2), c = 16.199(3) Å, β = 91.130(2)°, V = 1329.8(5) Å3, Z = 4. For III, a = 8.062(2), b = 8.599(2), c = 21.087(2) Å, β = 100.338(2)°, V = 1438.1(4) Å3, Z = 4. The Cu atom in each of the complexes is in square planar geometry. |
