Crystal and molecular structure of bis(4-Bromopyridine (cas 1120-87-2))dithiocyanate copper(II)

Add time:09/24/2019    Source:sciencedirect.com

The crystal structure of Cu(4-Brpy)2(NCS)2 exhibits two symmetrically independent pseudo-octahedral coordination polyhedra of Cu(II). The unit cell parameters are: a = 8.568(3), b = 9.200(3), c = 10.809(5) Å, α = 72.64(3), β = 86.15(3), γ = 80.14(3)°, triclinic symmetry, space group P1, Z = 2. The crystal structure data are discussed and compared with those of Cu(4-pic)2(NCS)2 and Cu(py)2(NCS)2. As the comparison shows, changed properties of the neutral ligands in these complexes do not influence the coordination mode of the thiocyanate ligand, but they manifest themselves in the different strength of its coordination to the central atom as also in the degree of axial distortion of the Cu(II) coordination polyhedra.
