A palladium(II) complex of 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine: Lattice control through an interplay of stacking and hydrogen bonding effects

The complex [Pd(1)Cl]Cl where 1 =  4′-(4-pyridyl)-2,2′:6′,2″-terpyridine is reported. The single crystal structure of [Pd(1)Cl]Cl · 3H2O · DMF features rows of columns of [Pd(1)Cl]+ cations which are supported by Pd⋯Pd interactions (3.367(1) and 3.440(1) Å) and separated by hydrogen-bonded 4.82 nets of water molecules and Cl− ions.
