Abstract

The polymeric structure of the title compound, poly[[diaquabis(mu-biphenyl-4,4'-disulfonato)tetrapotassium(I)] dihydrate], [[K2(C12H8O6S2)(H2O)].H2O]n, is based on an asymmetric unit comprising three independent and different potassium centres, one six-coordinate [K-O, 2.657(3)-2.886(5)A, one seven-coordinate [K-O, 2.703(3)-3.040(4)A], and the third ten-coordinate [K-O, 2.751(3)-3.079(4)A], with two of these lying on crystallographic mirror planes. The four half-occupancy water molecules also lie on the mirror planes with two coordinated (one monodentate, the other bidentate bridging) and two as molecules of solvation. The interlinked coordination polyhedra form chains which are joined laterally through the biphenyl residues as well as through hydrogen-bonding interactions, giving a two-dimensional structure.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
