چکیده
In the mixed-valence Cu(I)/Cu(II) coordination polymer, [Cu(2)Cl(3)(C(20)H(14)N(4))](n), the two Cu atoms are bridged to a pair of Cl atoms across a centre of inversion. The monovalent metal atoms is coordinated by a pyridine N atom as well as by three Cl atoms in a tetra-hedral CuNCl(3) geometry. The divalent metal atom is N,N',N''-chelated by the heterocycle, and it exists in a square-pyramidal CuN(3)Cl(2) geometry; the apical site is occupied by the second bridging Cl atom. The bridging modes of the Cl atoms and the heterocycle give rise to the formation of a layered arrangement parallel to (001).

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...

The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arran...

The Cu(II) atom in the title compound, [CuI(2)(C(20)H(14)N(4))], has a distorted square-pyramidal coordination formed by the N atoms of the tridentate 4'-(4-pyrid-yl)-2,2':6'2''-terpyridine (pyterpy) ligand and two I atoms; one of the I atoms is in the apical position. In contrast to other known square-pyramidal diiodido- and dibromidocopper complexes of the pyterpy ligand in which metal-haloge...

In the title complex, [Cu(C(20)H(13)BrN(4))(C(18)H(15)P)(2)]BF(4)·0.5CH(2)Cl(2), the copper(I) cation adopts a distorted tetra-hedral arrangement, coordinated by two triphenyl-phosphine ligands and two N atoms of the potentially tridentate terpyridine ligand. One half-mol-ecule of dichloro-methane crystallizes with the complex. The chlorine atoms are disordered over two sites with occupancies f...
