控制在1.00M條件下,[NiN7-Me](ClO4)2在0.50M硝酸溶液中,k1,k2,k3值分
別為 k1=(5.70*E-04*[H+])/(1+11.70*[H+]) s-1; k2=3.51*E-09/[H+]
+4.11*E-07 s-1; k3=(2.00*E-04*[H+])/(1+32.88*[H+]) s-1(二)在25.0
?.1?C, 離子強度控制在2.00M,六氮巨環鎳(II)錯化合物在甲酸乙酸磷
酸緩衝溶液系統中所進行的一般酸解離反應,其反應速率方程式如下:

(1) Kinetics of proton-catalyzed dissociation of
heptaazamacrocyclic nickel(II) complexes: The dissociation
kinetics of heptaazamacrocyclic nickel(II) complexes has been
studied spectrophotometrically in 0.50-0.01M HNO3 25.0?.1?c
and the ionic strength iis held at 1.00M. For [NiN7-Me](ClO4)2,
the resulting k1,k2,k3 value will be expressed as
followsk1=(5.70*E-04[H+])/(1+11.70*[H+]) s-1 : k2=3.51*E-09/[H+]
+ 4.11*E-07 s-1 ; k3=(2.00*E-04*[H+])/(1+32.88*[H+]) s-1 (2)
kinetics of general acid-catalyzed dissociation of
hexaazamacrocyclic nickel(II) complexes: The kinetics of general
acid-catalyzed dissociation of hexaazamacrocyclic nickel(II)
complexes are followed specrophotometrically at 25.0?.1?C and
?2.00M in formic acid-formate, acetic acid-acetate, phosphoric
acid-phosphorate buffer system
