Tetramethylcyclotetraarsoxane bridging of copper(I) halide units Cu6Br6, Cu2I2, [Cu6I8]2-, and 1∞[Cu3I4-] in porous coordination polymers

The polymeric compounds 1∞[{Cu2I2(C6H 5CN)2[cyclo-(CH3AsO)4]} · C6H5CN] (1) and 1∞[Cu6Br6(C6H 5CN)4{cyclo-(CH3AsO)4}] (2) may be prepared by reaction of the copper(I) halide with methylcycloarsoxane (CH3AsO)n in benzonitrile at 100 °C. 1 contains four-membered (CuI)2 rings, 2 tricyclic Cu6Br6 units, that are connected through bridging (CH3AsO)4 ligands into infinite chains. π-π Stacking of terminal C6H5CN ligands from parallel chains leads to the construction of porous frameworks, whose cavities are large enough in the case of 1 to accommodate guest C6H5CN molecules. In the presence of CsI, the self-assembly reaction of CuI with (CH3AsO)4 in H2O-CH3OH-CH3CN (at 20 °C) or CH3CN (at 13 °C) affords [Cs(H2O)2][Cu3I4{cyclo-(CH 3AsO)4}2] · 0.5 CH3OH (3) and Cs[Cu3I4{cyclo-(CH3AsO)4} 2] (4), whose 1- and 2-dimensional anionic coordination polymers are linked together through respectively [Cs{cyclo-(CH3AsO)4-K4O}2] + and [Cs{Cu3I4-K4I}{cyclo-(CH3AsO) 4-K4O}] sandwiches.
