Wj. Deng et al., MECHANISTIC STUDIES ON THE REACTION OF PENTAAQUAHYDROXOCHROMIUM(III) ION WITH OXALIC-ACID, Journal of chemical research. Synopses (Print), (5), 1998, pp. 248-249
The substitution of aqua ligands from pentaaquahydroxochromium(III) io
n by oxalic acid occurs through a mechanism involving the formation of
an ion pair followed by an associative interchange (I-a) process.
