Hexaaquazinc(II) bis(4-hydroxybenzenesulfonate) dihydrate
In the crystal structure of the title compound, [Zn(H2O)6](C6H5O4S)2·2H2O, the ZnII atom lies on a center of inversion. The complex cation interacts with the anion and uncoordinated water molecules by O-H
O hydrogen bonds, generating a three-dimensional network. The anion is disordered over two equal positions along the hydroxy-sulfonate C-C axis.
Sodium 3-carboxy-4-hydroxybenzenesulfonate (0.52 g, 2 mmol) was reacted with
zinc carbonate (0.25 g, 2 mmol) in water. The mixture was sealed in a 50-ml
Teflon-lined stainless-steel bomb and heat at 403 K for three days. The bomb
was then allowed to cool naturally to room temperature. Colorless prismatic
crystals were obtained. C&H elemental analysis. Calc. for
C12H26O16S2Zn: C 25.93, H 4.71%; found: C 25.97, H 4.77%. The
carboxyl group of sodium 3-carboxy-4-hydroxybenzenesulfonate was apparently
cleaved under the hydrothermal conditions.
The aromatic ring is disordered over two positions in respect of four carbon
atoms. 1,2-Related carbon-carbon distances were restrained to 1.39±0.01 Å
and the 1,4-related ones to 2.78±0.01 Å. Each component ring was restrained
to be nearly flat. As the disorder refined to nearly 1:1, the occupancy of the
disordered atoms was set as exactly 0.5.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 Å) and
were included in the refinement in the riding model approximation, with
U(H) set to 1.2U(C). The water and hydroxy H-atoms were refined
with a distance restraint of N–H 0.84±0.01 Å; their temperature factors
were refined.
