The Crystal Structure of 1,4-Bis(4-pyridyl)butadiyne and a Study of Its Complexes with Cobalt(II), Nickel(II) and Copper(II)

Abstract The diacetylene 1,4-bis(4-pyridyl)butadiyne has been prepared from 1-ethynyl pyridine. The purity of the 1,4-bis(4-pyridyl)butadiyne was confirmed by the melting point determination,1H NMR spectroscopy and by elemental analysis. A complete X-ray structure has been carried out on this compound. The preparation and some properties of complexes of 1,4-dis(4-pyridyl)butadiyne with cobalt, nickel and copper are described. Solubility studies, together with spectral and magnetic properties indicate that these compounds have polymeric octahedral structures.
