A new organic–inorganic hybrid compound,catena-poly[bis(1-ethyl-3-methylimidazolium) [μ5-bromido-tri-μ3-bromido-tri-μ2-bromido-pentacuprate(I)]], {(C6H11N2)2[Cu5Br7]}n, has been obtained under ionothermal conditions from a reaction mixture containing Ba(OH)2·8H2O, Cu(OH)2·2H2O, As2O5, 1-ethyl-3-methylimidazolium bromide and distilled water. The crystal structure consists of complex [Cu5Br7]2−anions arranged in sinusoidal {[Cu5Br7]2−}nchains running along theaaxis, which are surrounded by 1-ethyl-3-methylimidazolium cations. Three of the five unique Br atoms and one of the three CuIatoms occupy special positions with half-occupancy (a mirror plane perpendicular to thebaxis, site symmetrym). The CuIions are in a distorted tetrahedral coordination environment, with four Br atoms at distances ranging from 2.3667 (10) to 2.6197 (13) Å, and an outlier at 3.0283 (12) Å, exceptionally elongated and with a small contribution to the bond-valence sum of only 6.7%. Short C—H...Br contacts build up a three-dimensional network. The Cu...Cu distances within the chain range from 2.8390 (12) to 3.0805 (17) Å, indicating the existence of weak CuI...CuIcuprophilic interactions.

A new Lindqvist polyoxometalate-based hybrid compound with a helical chain structure, [Cu(bipy)2][W6O19] (1), (bipy = 2;20`-bipyridine), has been hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, thermogravimetry, and single-crystal X-ray diffraction. The compound crystallizes in the space group C2/c of the monoclinic system. In 1, the [W6O19]2- anions are connected alternately with [Cu(bipy)2]2+ subunits to form a meso-helical chain. To our knowledge, this structure represents the first example of a helical chain structure consisting of the hexatungstate anion [W6O19]2-. The electrochemical properties of the title compound have been studied.
