(2,2′-Bipyrimidine-κ2N1,N1′)diiodidopalladium(II)

Abstract

In the title complex, [PdI2(C8H6N4)], the PdII ion is four-coordinated in a slightly distorted square-planar environment defined by two pyrimidine N atoms derived from a chelating 2,2′-bipyrimidine (bpym) ligand and two mutually cis iodide anions. The nearly planar bpym ligand [maximum deviation = 0.053 (3) Å] is slightly inclined to the least-squares plane of the PdI2N2 unit [maximum deviation = 0.055 (2) Å], making a dihedral angle of 3.9 (2)°. In the crystal, pairs of complex molecules are assembled by intermolecular C—H...N hydrogen bonds into dimers. Intramolecular C—H...I hydrogen bonds are also observed.
