异羟肟酸钴(Ⅱ)配合物的合成及表征

Synthesis and Characterization of Hydroxamica Cobalt(Ⅱ) Complexes

合成了 4个N 取代异羟肟酸钴 (Ⅱ )配合物CoL2 (L1H =N [4 (2 乙酰氧基乙氧基 )苯甲酰基 ] N 苯基羟胺 ,L2 H =N (4 乙酰氧基苯甲酰基 ) N 苯基羟胺 ,L3 H =N 丁酰基 N 苯基羟胺 ,L4 H =N 乙酰基 N 苯基羟胺 ) ,并经元素分析 ,摩尔电导 ,红外光谱 ,UV ,XRD和差热分析等对它们进行了表征 .结果表明 :钴 (Ⅱ )与配体中的酰胺氧及去质子后的羟胺上的氧配位 .

Four cobalt(Ⅱ)complexes CoL 2(L 1H= N [4 (2 acetoxyoxethyl)benzoyl]phenylhydroxylamine, L 2H= N (4 oxethylbenzoyl)phenylhydroxylamine,L 3H=N hydroxy N phenyl acetamide, L 4H= N hydroxy N phenyl butanamide) were synthesized and characterized by elemental analyses,molar conductance,IR,UV ,XRD and DTA.In these complexes the hydroxamate ligands coordinate in the manner through carboryl oxygen atom and the deprotorated hydroxamate group.
