Abstract : The coordination compound of Fe( Ⅲ) with 2 ,22bipyridine - 1 ,12dioxide was synthesized , It was char2 acterized by elemental analysis , IR ,UV and molar conductivity. The gas sensitive property was studied ,the re2 sults indicated that the composition of the coordination compound is [ Fe(bipyO2) Cl2 ]Cl·1/ 6 bipyO2 . The sensor manufactured by coordination compound has very high sensitivity and selectivity to ammonia. It could be used in ammonia leak2alarm and in environment realtime supervising ammonia.
