Porous copper(I) coordination polymers containing both the cyclic ion ligating agent methylcycloarsoxane (MeAsO)4 and rigid aromatic heterocycles as spacers

Abstract

Porous lamellar networks with flexible [Cu_xI_y{cyclo-(MeAsO)₄}] ribbons bridged by either π–π stacked terminal benzonitrile ligands (x = y = 2), rigid p-diaminobenzene spacers (x = y = 2) or ionic [Cs{cyclo-(MeAsO)₄}₂]⁺ sandwiches (x = 3, y = 4) may be constructed by self-assembly from CuI and (MeAsO)_n in the presence of the respective structure-directing agents.
