`AgNO_(3)` solution will not give white precipitate with

An isomerr of the complex CoBrCl_(2)(en)_(2)(H_(2)O) , on reaction with concentrated H_(2)SO_(4) (dehydrating agent), suffers no loss in weight and on reaction with AgNO_(3) solution it gives only white precipitate, which is soluble in NH_(3) solution. Q. The incorrect statement about complex is:
