Two coordination isomers are P = [Co(NH₃)₆][Cr(CN)₆] and Q = [Cr(NH₃)₆][Co(CN)₆]. Keep both metals +3 and use low-spin Co(III) and d³ Cr(III). Which statements hold for BOTH salts?

Question

NH₃ is neutral and six CN⁻ give an anion of −3 at M(III). Co(III), low-spin d⁶, is t 2 g ​ ⁶; Cr(III), d³, is t 2 g ​ ³. Ligand exchange between metal centres changes neither these stipulated configurations nor the charge magnitudes. Homoleptic Ma₆ ions have no cis/trans alternatives.
