AI Article Synopsis
- The compound BaZnAs(2)O(7) is part of a broader series with a general formula involving different metal ions (M1 and M2) and anions (X), with Ba and Zn being specific examples.
- Single crystals of BaZnAs(2)O(7) were synthesized using hydrothermal methods and exhibit a structure made of corner-sharing ZnO(5) square pyramids and As(2)O(7) groups.
- X-ray diffraction confirmed the compound's identity and structure, and Raman spectroscopy indicated the existence of a unique As-O-As linkage within the framework.
Article Abstract
The title compound, BaZnAs(2)O(7), belongs to the family of isotypic series of compounds adopting the general formula M1(2+)M2(2+)X(2)O(7) (M1(2+) = Ca, Sr, Ba or Pb; M2(2+) = Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn or Cd; X = P or As). Suitable single crystals were prepared under hydro-thermal conditions. The framework structure is characterized by corner-sharing ZnO(5) square pyramids and As(2)O(7) groups where the Zn atoms occupy channels. X-ray diffraction analysis of single crystals twinned by non-merohedry [twin plane is (100)] yielded formula BaZnAs(2)O(7). Raman spectra confirmed the presence of a non-linear As-O-As linkage.
