A nitrilotriphenolato complex ([Ge2(ntp)2O]) with three coordinating phenolates around Ge(IV) showed a sub-Nernstian response (40 mV/decade) to fluoride in the range of 10-3?10-1 mol dm-3 as a carrier of ion-selective electrodes(ISEs). The dynamic range was extended to 10-4?10-1 mol dm-3 in the presence of cationic additives. Spectroscopic studies on the reaction of this complex with anions in dimethyl sulfoxide demonstrated the reaction stoichiometry of Ge(IV) : A- = 1 : 1 and the thermodynamic stability order of F- > CH3COO- > H2PO4-. The reaction selectivity agreed with that of potentiometry with ISEs. A bis(catecholato) complex with four phenolates showed no response to anions, and a bis(aminophenolato) complex with two phenolates was not stable enough in the reaction with anions., application/pdf}, pages = {1035--1038}, title = {ゲルマニウム(IV)錯体のアニオノフォアとしての特性}, volume = {53}, year = {2004}, yomi = {ヤスイ, タカシ and ユチ, アキオ} }
