KINETICS OF ANATION OF CIS-DIAQUO-BIS-(1,3-DIAMINOPROPANE) COBALT(III) BY OXALATE

Thermal and photochemical reactions of bis(diamine)(sulfito)cobalt(III) complexes: effect of chelate-ring size

“…The complex cis-[Co(tn) 2 (CO 3 )]ClO 4 was prepared as reported; 18 cis-[Co(tn) 2 (OH 2 ) 2 ] 3ϩ was generated in situ by acidifying the solution of the carbonato complex, dissolved CO 2 being expelled by bubbling N 2 . The solution of the aqua complex ([complex] T = 0.05 mol dm Ϫ3 , pH 2) was stored at 10 ЊC in a refrigerator {λ max /nm (ε/dm 3 mol Ϫ1 cm Ϫ1 ): 508 (56) and 358 (69); lit., 510 (62), 360 (78), 19 505 (55.2), 362 (67.7) 18 for cis-[Co(tn) 2 (OH 2 ) 2 ] 3ϩ }.…”
