Abstract
Zinc(II) reacts with the anion of 3-cyano-2,4-pentanedione to form the coordinatively unsaturated bis(β-dionato)zinc(II) chelate that functions as Lewis acid and induces short-range site-bounded cohesion forces. Water molecules add to the metal center while others participate in specific interactions involving the terminal nitrogen atom. The X-ray structure analysis of the [Zn(H2O)2(NC-acac)2] · 2H2O entity (monoclinic, space group P21/c, a = 5.208(5), b = 21.359(5), c = 7.813(5) Å, β = 101.89(3)°, Z = 4, R = 0.0632, Rw = 0.0679) revealed that zinc(II) exists in a centrosymmetric distorted tetragonal environment and that the entity performs as a building block of a supramolecular structure.
