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

In the polymeric title compound, {[Na(C10H9N4O4S)(H2O)(3)]center dot 2H(2)O}(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 center dot center dot center dot O, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds and additional pi-pi interactions connect these chains into a three-dimensional network.
