highest electronegativity. How the radius ratio is related with the co-ordination number and structure of ionic crystal? Ans. The permitted coordination number and structural arrangement of anions around cations for different rIr ratio are given in Table: Limiting Radius Ratio, r Permitted Co- Structural Example ordination Numbe r Arrangement 0-155 0 255 3 Plane Trigonal BO3 0-255-0-414 4 Tetrahedral ZnS 0-414-0.732 6 Octahedral NaCl 0-732 1.00 8 Cubic CsCI
