Abstract:
The title dimethyl sulfoxide solvate, [Hg 2 (C 12 H 9 ClN 2 )I 2 ]·C 2 H 6 OS, features tetrahedrally and linearly coordinated Hg II atoms. The distorted tetrahedral coordination sphere is defined by chelating N atoms that define an acute angle [69.6 (3)°] and two I atoms that form a wide angle [142.80 (4)°] . The linearly coordinated Hg II atom [177.0 (4)°] exists with a donor set defined by C and Cl atoms. Secondary interactions are apparent in the crystal packing with the tetrahedrally and linearly coordinated Hg II atoms expanding their coordination environments by forming weak Hg...I [3.772 (7) Å] and Hg...O [2.921 (12) Å] interactions, respectively. Mercury-containing molecules stack along the a axis, are connected by π–π interactions [inter-centroid distance between pyridine and benzene rings = 3.772 (7) Å] and define channels in which the dimethyl sulfoxide molecules reside. The latter are connected by the aforementioned Hg...O interactions as well as C—H...I and C—H...O interactions, resulting in a three-dimensional architecture.
