Which of the following compounds has a meridional isomer?(a) [Fe(NO)5B

1.	Which of the following compounds has a meridional isomer?(a) [Fe(NO)5Br]^+(b) [Al(CO)3(NO2)3](c) [K(NH)3)4(NO)2]^+(d) [Fe(H2O)2(CO)2(NO)2]^3+The question was posed to me in quiz.The query is from Isomerism in Coordination Compounds topic in division Coordination Compounds of Chemistry – Class 12
Answer» RIGHT answer is (B) [Al(CO)3(NO2)3] The best I can EXPLAIN: Fac-mer isomerism is only exhibited in octahedral coordination ENTITIES of the type [MA3B3] depending on the positions of the similar LIGANDS.
