Tetraaquabis(4,4'-bipyridine)zinc(II) bis(trans-4-hydroxycinnamate)

L. Chen

Abstract: The title complex, [Zn(C₁₀H₈N₂)₂(H₂O)₄](C₉H₇O₃)₂, was obtained by the hydrothermal reaction of zinc sulfate with mixed 4-hydroxylcinnamic acid (H₂L) and 4,4'-bipyridine (4,4'-bipy) ligands. The complex consists of a centrosymmetric [Zn(4,4'-bipy)₂(H₂O)₄]²⁺ cation with the metal centre in a distorted ZnN₂O₄ coordination, and of two HL^- anions. Extensive O-HO and O-HN hydrogen-bonding interactions between the constituents lead to the formation of a three-dimensional network.
