Syntheses, X-ray crystal structures and spectroscopic characterization of rare μ-di-σ pyrazole based bridging keto carbonyl complexes derived from Cd(II) salts

Three new rare keto oxygen bridged Cd(II) complexes have been prepared from the pyrazole based ligands N-PzOPyH and PzOPyH, and Cd(II) metal precursors. They have been synthesized and characterized both structurally and spectroscopically. These rare keto bridged Cd(II) complexes are stabilised by supramolecular interactions, like π⋯π, C-H⋯π and H-bonding interactions.
