A metal complex having composition [Cr(NH_(3))_(4)Br_(2)] was isolated in two forms (X) and (Y). Form (X) reacts with AgNO_(3) to gives a plate yellow precipitate which is partially soluble in excess of NH_(4)OH whereas (Y) gives a greenish yellow precipitate which is insoluble in NH_(4)OH. The hybridization of Cr ini X and Y both are
