The one-dimensional chain polymer of aqua(tyrosinato)zinc(II).
In the title compound, catena-poly[[aquazinc(II)]-micro(3)-tyrosinato], [Zn(C(9)H(7)NO(3))(H(2)O)](n), each Zn atom has a distorted square-pyramidal geometry comprised of three O atoms and one N atom from three tyrosinate (tyr) ligands, and one aqua ligand. Two inversion-related Zn(2+) ions are bridged by two O atoms from the phenolate groups of two tyr ligands to form a centrosymmetric dimeric unit, which can be described as a planar Zn(2)O(2) four-membered ring. These repeating dimeric units are arranged along the c axis to give a one-dimensional chain coordination polymer, in which the tyr ligand adopts an unusual chelating/bridging coordination mode.
