Classify the following isomers of coordination compounds into symmetry point gro

Question

Classify the following isomers of coordination compounds into symmetry point groups: cis- [PtCl_2(NH_3)-2] and trans- [PtCI_2(NH_3)_2]. For this purpose, assume that the NH_3 groups rotate freely so that the hydrogens do not lower the symmetry of these complexes. Classify the following isomers of coordination compounds into symmetry point groups mer-[CoCl_3(NH_3)_3] and fac-[CoCl_3(NH_3)_3). (The fac and mer isomers are illustrated in illustrated in Fig. 9.10 (c and d).] Assume that the NH_3 groups rotate freely.

Explanation / Answer

cis-[PtCl2(NH3)2] are polar in nature and no one is chiral.

cis-[PtCl2(NH3)2] have C2vpoint group and trans-[PtCl2(NH3)2] have D2h point group.

mer-[CoCl3(NH3)3 ] have C2v point group and fac-[CoCl3(NH3)3] have C3v point group.
