Synthesis, Crystal Structure and Property Studies on a Bipyridine Adduct of Nickel Xanthogenate

A new coordination polymer containing mixed ligands, namely [Ni(S(2)COiBu)(2)(DBPMF)center dot(CHCl3)](infinity) (DBPMF = 2,7-dibromo-9,9-(4-pyridylmethyl)fluorine), has been synthesized and structurally characterized by elemental analysis and single-crystal X-ray diffractions. X-ray structural analysis reveals that each Ni atom is coordinated by two isobutyl xanthogenate molecules and two nitrogen atoms from two DBPMF ligands to form octahedral coordination geometry. DBPMF acts as a bridge to form a coordination polymer. Fluorescence property of this coordination polymer displays a broad emission band at lambda = 413 nm. Thermal analysis shows that the solvent molecule CHCl3 can be stabilized in the crystal structure until 140 degrees C.
