Abstract
Single-crystal XRD and Raman spectroscopy were used to characterize the crystal structure and vibrational properties of BaCuSi (sub 2) O (sub 6) , a new silicate structure type with isolated 4-rings of tetrahedra and square-plane-coordinated Cu. This new phase, synthesized inadvertently in the search for high-T superconductors, possesses only seven variable structure parameters and thus is one of the simplest of all known cyclosilicates.
