Question

If co-ordinates of a point charge (ligand) in tetrahedral complex is ( $+ x, - y, - z$ ) then what are the co-ordinates of other three point charges (ligands) of tetrahedral complex, if all point charges are present at corner of cubes.

(If central atom is placed at origin) ?

(P) $(+ x, - y, + z)$

(Q) $(- x, - y, + z)$

(R) $(- x, + y, - z)$

(S) $(+ x, + y, + z)$

The four vertices of a regular tetrahedron inscribed in a cube are alternate corners of the cube. If one corner is $(+ x, - y, - z)$ (two negative signs), the other corners of the same tetrahedral set also carry an even number of negative signs:

$(- x, + y, - z), (- x, - y, + z), (+ x, + y, + z)$

These are (Q), (R) and (S). Point (P) $(+ x, - y, + z)$ has one negative sign and belongs to the opposite tetrahedral set.

Answer: (C) - Q, R, S
