What is the C.N. of octahedral void ?

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

The total number of tetrahedral voids in the face-centred unit cell is-

Number of tetrahedral voids in a face-centred cubic unit cell is-

In a crystalline solid, having formula AB_(2)O_(4) oxide ions are arranged in cubic close packed lattice while cations A are present in tetrahedral voids and cations B are present in octahedral voids. (a) What percentage of the tetrahedral voids is occupied by A? (b) What percentage of the octahedral voids is occupied by B ?

Is the shape of a tetrahedral void tetrahedral? If not, why is it so called?

The regular three dimensional arrangement of points in a crystal is known as crystal lattice and the smallest repeating pattern in the lattice is called unit cell. The unit cells are characterised by the edge lengths a, b, c and the angles between them alpha, beta and gamma respectively. Based on this, there are seven crystal systems. In a cubic unit cell: a=b=c and alpha = beta=gamma=90^(@) The number of points in simple, body centred and face centred cubic cells are 1,2 and 4 respectively In both the hcp and ccp of spheres, the number of tetrahedral voids per sphere is two while the octahedral voids is one. The C.N of cation occuppying an octahedral vois is:
