B. Paluchowska et al., THE ROLE OF C-H-CENTER-DOT-CENTER-DOT-CENTER-DOT-O BONDS IN STABILIZING 3-FURANCARBOXYLIC ACID AND ITS COMPLEXES WITH CALCIUM AND STRONTIUM, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 342-347
The crystal structures of 3-furancarboxylic acid, C5H4O3, and both its
calcium and strontium complexes, aquacalcium-mu-(3-furancarboxylato-O
,O':O)-mu-aqua 3-furancarboxylate], [Ca(C5H3O3)-(H2O)(3)](C5H3O3), and
uastrontium-mu-(3-furancarboxylato-O,O':O)-mu-aqua 3-furancarboxylate
], [Sr(C5H3O3)(H2O)3](C5H3O3), respectively, are presented, The differ
ences and similarities in the hydrogen-bonding schemes of the title ac
id and 2-furancarboxylic acid are discussed, and the importance of C-H
...O hydrogen bonds in the crystal packing of 3-furancarboxylic acid a
nd its strontium and calcium complexes is highlighted.
