The title compound, BaZnAs2O7, belongs to the family of isotypic series of compounds adopting the general formula M12+M22+X2O7 (M12+ = Ca, Sr, Ba or Pb; M22+ = Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn or Cd; X = P or As). Suitable single crystals were prepared under hydrothermal conditions. The framework structure is characterized by corner-sharing ZnO5 square pyramids and As2O7 groups where the Zn atoms occupy channels. X-ray diffraction analysis of single crystals twinned by non-merohedry [twin plane is (100)] yielded formula BaZnAs2O7. Raman spectra confirmed the presence of a non-linear As-O-As linkage.
