摘要

In the title compound, [Cd(C2H8N2)(2)(H2O)(2)](C10H8NO3S)(2)center dot-2H(2)O, the Cd-II atom, located on an inversion centre, has a distorted octahedral coordination geometry formed by two ethylenediamine and two water molecules. 4-Aminonaphthalene-1-sulfonate acts as a counter-ion to balance the charge, and two antiparallel anions showing strong pi-pi stacking interactions are linked by paired N-H center dot center dot center dot O(sulfonate) hydrogen bonds into an isolated R-2(2)(16) dimer. The crystal structure is stabilized by the pi-pi stacking interactions and hydrogen bonds.
