Abstract
The crystal structures of two unreported CdII complexes with different dinitrogenated bases and the unusual peroxodisulfate anion (pds, S2O8 2-) are presented: Cd(pds)(phen)2(H2O)·H2O and Cd(pds)(dmph)2 (phen = 1,10- phenanthroline; dmph = 2,9-dimethyl-1,10-phenanthroline). Both compounds are monomeric. In the first, the anion acts as a monodentate ligand, as in all previously reported structures where it binds to a cation, while in the second it displays novel chelate behaviour. Both structures are stabilized by hydrogen-bonding networks, with mediumstrength interactions mediated by aqua and hydration water molecules in the first case and much weaker ones provided by C–H⋯O contacts in the second. Compound (1) is triclinic, P1-, a 8.745(3), b 9.260(5), c 17.564(3) Å, α 96.80(2), β 101.581(3), γ 105.97(3)°, V 1316.6(9) Å3, Z 2, R 0.044, No 4384. Compound (2) is monoclinic, Cc, a 22.233(12), b 9.566(5), c16.017(8) Å, β 123.78(3)°, V2831(3) Å3, Z 4, R 0.024, No 2363.
