二甲氧基嘧啶胺与金属盐配合物的恒容燃烧热测定

在无水乙醇中 ,使钴、铜、锌、锰的盐与二甲氧基嘧啶胺 (AMP)反应 ,回流数小时后 ,浓缩、冷却 ,抽滤 ,制得了 6种二甲氧基嘧啶胺与钴、铜、锌、锰的固态配合物 .用化学分析和元素分析确定了它们的组成 ,分别为Co(AMP) 2 Cl2 ( 1) ,Cu(AMP) 2 Cl2 ( 2 ) ,Cu(AMP) 2 (NO3 ) 2 ( 3 ) ,Zn(AMP) 2 Cl2 ( 4 ) ,Mn(AMP) 2 Cl2 ( 5 )和Zn(AMP)SO4( 6) ;用IR ,1 HNMR研究了他们的成键情况 ;用精密转动弹热量计测定了配体及配合物的恒容燃烧热ΔcU ,计算了它们的标准摩尔燃烧焓ΔcHθm 和标准摩尔生成焓ΔfHθm.

Co(AMP)_2Cl_2的合成及表征

Amino 4,6 dimethoxypyrimidine(AMP) was synthesized using benzyltriethyl ammonium chloride(BTEA) as a catalyst in yield of 87 5%. A solid complex Co(AMP) 2Cl 2 was obtained by refluxing AMP with CoCl 2 in ethanol. The composition of the complex was determined by chemical and elemental analyses. The structure of the complex and sp 3 d 2 of the hybridization type of Co 2+ were estimated by IR, XPS and 1H NMR.
