چکیده
The reaction of CdCl(2), 18-crown-6 and KI in water yields the title coordination polymer, [{K(C(12)H(24)O(6))}(2)Cd(2)I(6)](n). The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77 (2) and 0.23 (2). Two K(18-crown-6)(+) units are linked by inversion symmetry, forming a [bis-(μ(2)-18-crown-6)dipottasium] system with approximately square-planar K(2)O(2) units. Inversion symmetry also generates the Cd(2)I(6) fragment and the polymeric system is extended along the c axis by the formation of K-I-Cd bridges.

In the title compound, [Cu(3)I(3)(C(5)H(5)NS)(3)](n), a polymeric structure is formed along [100] through bridging iodide and pyridine-2-thione ligands. The metal atoms are engaged in [Cu(3)S(3)] and [Cu(2)S(2)] rings sharing Cu-S edges, with the [Cu(2)S(2)] rings located about inversion centers. Cu(I) atoms bridged by iodide ions exhibit the shortest Cu⋯Cu separation in the polymer [2.8590 (14...

The reaction of copper(I) iodide with N-acetyl-thio-morpholine (L, C6H11NOS) in aceto-nitrile results in a coordination polymer with composition [CuI(L)2] n . The CuI atom is coordinated by two S atoms and two I atoms, adopting a distorted tetra-hedral environment. The μ2-bridging mode of the I atoms gives rise to chains extending parallel to [010]. C-H⋯O hydrogen-bonding inter-actions between ...
متن کاملCrystal structure of di-μ-iodido-bis[(dimethyl sulfoxide-κO)(triphenylphosphane-κP)copper(I)]
The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu⋯Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals r...

In the centrosymmetric tetra-nuclear title compound, [Cu(4)I(4)(C(10)H(8)N(2)S(2))(2)], there are two different Cu(I) atoms with tetra-hedral coordination geometries. One is chelated by a pyridine N atom and an S-donor from one di-2-pyridyl disulfide ligand and coordinated by two I atoms, while the second Cu(I) atom is coordinated by a pyridine-N and three I atoms. Iodine bridges between the Cu...
