molecular vibrational constants and chemical bonding in the cyclic oxocarbon dianions Cnon-2(n=3, 4 and 5)
(1988)
By means of an ab initio force field and the mean amplitudes of vibration of the cyclic oxocarbon dianions Cn0nwith n= 3, 4 and 5, it has been found that the ground-state aromaticity order in the series is: deltate (n=3) ...
Raman spectra of a pseudo-oxocarbon anion in ionic liquids
(JOHN WILEY & SONS LTD, 2010)
Raman and electronic spectra of the [3,5-bis(dicyanomethylene)cyclopentane-1,2,4-trionate] dianion, the croconate violet (CV), are reported in solutions of ionic liquids based on imidazolium cations. Different normal modes ...

Spectroscopic investigation of a new hybrid glass formed by the interaction between croconate ion and calcium polyphosphate
(Elsevier B.V., 2005-07-01)
In this work, a new organic-inorganic hybrid material has been synthesized by the incorporation of croconate ion into a calcium polyphosphate coacervate. The hybrid so obtained was characterized by means of electronic and ...
