Abstract

The structure of NaZnSiO(3)OH, synthesized hydrothermally by reaction of Na(2)ZnSiO(4) and NaOH, has been determined from single-crystal X-ray and powder neutron diffraction data (orthorhombic, space group P2(1)2(1)2(1,) a = 7.6872(2) _, b = 9.3899(2) _, c = 5.155(1) _, Z = 4). The structure has a framework constructed from ZnO(4) and SiO(3)OH tetrahedra with bridging and trigonal oxygen atoms. Channels formed from eight-membered rings of tetrahedra house the sodium ions and are also partially blocked by moderately strongly hydrogen bonded OH groups.
