Dichlorobis(thiourea)zinc(II) bis(4,5-diazafluoren-9-one)

Z.-Y. Wu, D.-J. Xu and K.-L. Yin

Abstract: The title compound, [ZnCl₂(CH₄N₂S)₂]·2C₁₁H₆N₂O, consists of the tetrahedral ZnCl₂-thiourea complex and hydrogen-bonded 4,5-diazafluoren-9-one (dafone). The NN distance in dafone when not involved in metal coordination is significantly larger than when it is metal chelating. Neighboring zinc(II) complex molecules hydrogen bond to each other, forming supramolecular chains. - stacking is observed between neighboring dafone rings.
