Coupled with chemical analysis, a single-crystal X-ray structure determination of lilac deposit from a swimming pool, shows the deposit to be the title compound Na2CU(C3H2N3O3)4.6H2O. Crystals are triclinic, P1BAR, a 10.459(1), b 10.434(3), c 6.762(4) angstrom, alpha 71.73(4), beta 83.67(4), gamma 62.82(2), Z 1 formula unit; 1265 'observed' diffractometer reflections were refined to R 0.052. The copper atoms are located on crystallographic inversion centres, four-coordinated by a pair of water molecules [Cu-O, 1.937(6) angstrom] and a pair of ligand nitrogen atoms [Cu-N, 1.941(9) angstrom]. Interactions from ligand oxygen atoms to sodium ions link the structure into a polymeric array.
