Write the formula for the following coordination compounds. (a) potasiumhexacyanidoferrate (II) (b) petacarbonyliron (0) (c ) pentaamminenitrito - k -N-cobalt (III) ion (d) hexaamminecobalt (III) sulphate (e ) sodiumtetrafluoridhydroxidochromate (III)

Answer»

Solution :`(a)` potasiumhexacyanidoferrate (II)`=K_(4)[Fe(CN)_(6)]`
`(b)` petacarbonyliron (0) `=[Fe(CO)_(5)]`
`(c )` pentaamminenitrito - k -N-cobalt (III) ion `=[Co(NH_(3))_(5)NO_(2)]^(2+)`
`(d)` HEXAAMMINECOBALT (III) sulphate `=[Co(CN)_(6)]_(2)(SO_(4))_(3)`
`(e )` sodiumtetrafluoridhydroxidochromate (III) `=Na_(3)[CrF_(4)(OH)_(2)]`
