Research output: Contribution to journalArticle


The title compound exists as a 1D coordination polymer consisting of alternating calcium cations and croconate anions. Three water molecules complete the 7-coordination sphere of Ca in the form of a pentagonal bipyramid and form hydrogen bonds which link the polymeric chains into layers and also interconnect the layers. The structure has a triclinic space group P-1 with a = 6.642(3)Angstrom, b = 7.793(4)Angstrom c = 8.854(5) Angstrom, alpha = 106.97(5), beta = 92.43(4), gamma = 106.98(4)degrees, V = 415.1(4) Angstrom(3), and Z = 2.
