The Cu(II) atom in the title compound, [CuCl2(C14H21F3N4)], adopts a coordination geometry that is between distorted square-based pyramidal and very Jahn-Teller-elongated octa-hedral. It is coordinated by three N atoms from the bis-(2-amino-eth-yl)(2-{[4-(tri-fluoro-meth-yl)benzyl-idene]amino}-eth-yl)amine and two chloride ligands. The two(More)
The structures of five compounds consisting of (prop-2-en-1-yl)bis[(pyridin-2-yl)methylidene]amine complexed with copper in both the Cu(I) and Cu(II) oxidation states are presented, namely chlorido{(prop-2-en-1-yl)bis[(pyridin-2-yl)methylidene]amine-κ(3)N,N',N''}copper(I) 0.18-hydrate, [CuCl(C15H17N3)]·0.18H2O, (1),(More)
The five-coordinate Cu(II) atom in the title complex [CuCl2(C16H19N3)]·0.5C4H10O, adopts a near-ideal square-pyramidal geometry (τ-5 = 0.01). The apical Cu-Cl distance is 0.2626 (6) Å longer than the basal Cu-Cl distance. Weak C-H⋯Cl interactions between pyridine rings and the Cl atoms of adjacent complex molecules are present. The solvent molecule, located(More)
In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the Cu(II) ion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitro-gen atoms from the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221(More)
In the asymmetric unit of the title compound, [CuBr(C18H18N4)]Br, there are three crystallographically independent cations. One of the cations exhibits positional disorder of the pyridin-2-yl-methyl groups over two sets of sites with refined occupancies of 0.672 (8) and 0.328 (8). The outer-sphere bromine counter-ion is severely disordered over multiple(More)
