It was noted that this material crystallized in a monoclinically distorted tri-rutile structure with a nearly square planar Cu2+ lattice, but in which the spin system was quasi 1-dimensional. Single crystals of up to 125mm3 were grown by chemical vapor transport, with TeCl4 as a transport agent. The crystals grew, from the gas phase, in the tetragonal modification and transformed into the monoclinic modification upon cooling to room temperature. This resulted in twinning of the crystals. Uniaxial pressure treatment at up to 30MPa failed to de-twin the crystals.
