NettetThe radius ratios are r+/r = 74/170 = 0.435 for the CN = 4andr+/r = 88/170 = 0.518 for the CN = 6 radius. Both predict CN = 6, but the smaller one is close to the tetrahedral limit of 0.414. Experimentally, the Zn cation fits into the tetrahedral holes of the lattice, which is either ccp (zinc blende) or hep (wurtzite). Nettet5. apr. 2024 · Hint: Tetrahedral carbon is basically a carbon atom with four attachments and the carbon atom uses orbitals to achieve this geometry. Basically the radius ratio …

NettetSolution: The radius ratio is the ratio of the radius (r) of the atom or ion which can exactly fit in the octahedral void formed by spheres of radius R. For trigonal voids, the radius ratio is 0.155. For tetrahedral voids, the radius ratio is 0.225. For octahedral voids, the radius ratio is 0.414. For cubic voids, the radius ratio is 0.732. Thus, the limiting …
