摘要:

在常温下合成了以邻苯二酚为配体,分别以乙二胺、1,2-丙二胺、1,3-丙二胺为抗衡离子的7种手性钼钨八面体配合物(NH2CH2CH2NH3)3[Mo(V)O2(OC6H4O)2] (1),(NH2CH2CH2NH3)2[W(VI)O2(OC6H4O)2] (2),(NH2CH2CH2NH3)2.5[Mo(V)0.5W(VI)0.5O2(O2C6H4)]2] (3),(NH3CH2CHNH2CH3)3[Mo(V)O2(OC6H4O)2] (4),(NH3 CH2CHNH2CH3)2[W(VI)O2(OC6H4O)2] (5),(NH3CH2CHNH2CH3)2.5[Mo(V)0.5W(VI)0.5O2(OC6H4O)2] (6),(NH3CH2CH2CH3NH2)2.5[Mo(V)0.5W(VI)0.5O2 (OC6H4 O)2] (7),并在生理条件下对其与ATP的相互作用进行了液体NMR研究,发现标题配合物的中心金属离子在纯D2O溶剂中大多数以+5价形式存在,W(VI)被还原为W(V),但与ATP混合后又转化为+6价,配合物原有的顺磁性特征完全消失. 研究还发现ATP可以促进中心离子与原配体发生解离.

Abstract:

Seven molybdenum and tungsten octahedral complexes, with benzene-1,2-diol as a ligand and ethylenediamine 1, 2-diaminopropane and 1, 3-diaminopropane as counterions, respectively, were synthesized under normal temperature. The interactions between adenosinetriphosphate (ATP) and these compounds: (NH2CH2CH2NH3)3[Mo(V)O2(OC6H4O)2] (1),(NH2CH2CH2NH3)2[W(VI)O2(OC6H4O)2] (2),(NH2CH2CH2NH3)2.5[Mo(V)0.5W(VI)0.5O2(O2C6H4)]2] (3),(NH3CH2CHNH2CH3)3[Mo(V)O2(OC6H4O)2] (4),(NH3 CH2CHNH2CH3)2[W(VI)O2(OC6H4O)2] (5),(NH3CH2CHNH2CH3)2.5[Mo(V)0.5W(VI)0.5O2(OC6H4O)2] (6),(NH3CH2CH2CH3NH2)2.5[Mo(V)0.5W(VI)0.5O2 (OC6H4 O)2] (7) were studied by LC-NMR. The results showed that the valence of the center ions were +5 when the complexes were dissolved in D2O and the reduction of W(VI) to W(V) occurs . W(V)  could be oxidized again when ATP solution was mixed with the original solution and hydrolysis of benzene-1,2-diol ligand took place.
