Synthesis and crystal structure of catena-poly[[[aqua{2-[(E)-(1-cyano-2-imino-2-methoxyethylidene)hydrazinyl]benzenesulfonato}sodium]-di-μ-aqua] dihydrate]

Abstract

In the polymeric title compound, {[Na(C10H9N4O4S)(H2O)3]·2H2O} n , sixfold coordinated Na+ cations are linked into a chain parallel to [010] by sharing common water molecules. Next to the four bridging water molecules, each Na+ cation of the chain is bonded to the O atom of a terminal water molecule and an O atom of the SO3 − group of the sulfonate anion. Classical O—H...O, O—H...N and N—H...O hydrogen bonds and additional π–π interactions connect these chains into a three-dimensional network.
