Abstract

Structure of polymorphic Er2Si2O7 single crystal grain is determined using X-Ray diffrectiometer (Bruker Kappa ApexII). Crystal structure is refined through the use of software Shelxl. Findings declared also three dimensional view of the compound under study. The crystal crystallizes in space group (C2/m) with monoclinic symmetry. Bond length between erbium and oxygen is 2.24(A0), bond length of oxygen and silicon is 1.62(A0). The bond angle between Er-O-Er is 1010, O -Er-O is 85.130 and Er -O1
