The current article investigated the effects of ammonia nitrogen concentration and pH on peroxidation damage and antioxidative capability of Ceratophyllum demersum.The pH ranges (7 and 9) were carefully controlled to distinguish between the effects of unionized ammonia(NH3) and ionized ammonia (NH4+).The addition of ammonia significantly decreased chlorophyll a content.Peroxidase and superoxide dismutase activities as well as glutathione content under high ammonia conditions (10 mg N/L) significantly increased at pH 7 but were no different or reduced at pH 9.Catalase activity as well as ascorbic acid and malondialdehyde contents significantly increased under all ammonia treatments at pH 7 and 9.C.demersum suffered from stre at pH 9 under high ammonia conditions.Higher pH in water may induce C.demersum to exhibit more severe physiological responses.*马娜，2011级本科生，学号20112310317，在本论文中为第二作者。 *国家自然科学基金资助项目（No.J1210060)

The Ag(I) and Cu(I) complexes of 4-amino-3,5-dipentyl-4H-1,2,4-triazole (4-NH2-3,5-(C5H11)2tz) and 3,5-dipentyl-1H-1,2,4-triazole (3,5-(C5H11)2tzH) have been synthesized and characterized.X-Ray analysis shows that {Ag4[4-NH2- 3,5-(C5H11)2tz]6}(BF4)4 is a tetranuclear complex featuring an Ag4tz6 cluster; {Ag[3,5-(C5H11)2tz]}n exhibits a 3D structure of lvt-a topology; and {Cu2[3,5- (C5H11)2tz]Br}n is a Cu4Br4-cluster based 3D complex with the dia topology.
