Abstract

The title compound, [PdCl(2)(C(6)H(16)N(3))](C(7)H(7)SO(3)), consists of a Pd(II) atom bonded to two N atoms of the 1,4,7-triaza-cyclo-nonane (TACN) ligand and two chloride ions, which define a distorted square-planar geometry. The third N atom of the TACN ligand is protonated and hydrogen bonds to the p-toluene-sulfonate anion. The Cl-Pd-Cl angle is larger than the N-Pd-N angle. The packing is dominated by layers, which are formed by the criss-crossing of two different hydrogen-bonded chains. One chain is composed of hydrogen-bonded Pd(TACNH)Cl(2) (+) cations, while the second is formed through hydrogen bonding between the p-toluene-sulfonate anion and the Pd(TACNH)Cl(2) (+) cation.
