A fivefold interpenetrating diamond-like three-dimensional metal-organic framework: poly[(μ2-benzene-1,4-diacetato)[μ2-1,6-bis(1,2,4-triazol-1-yl)hexane]zinc(II)].

In the mixed-ligand metal-organic title polymeric compound, Zn(C(10)H(8)O(4))(C(10)H(16)N(6)) or Zn(PBEA)(BTH) [H(2)PBEA is benzene-1,4-diacetic acid and BTH is 1,6-bis(1,2,4-triazol-1-yl)hexane], the asymmetric unit contains a Zn(II) atom, one half of a BTH ligand and one half of a doubly deprotonated H(2)PBEA ligand. Each Zn(II) centre lies on a crystallographic twofold rotation axis and is four-coordinated by two O atoms from two distinct PBEA(2-) ligands and two N atoms from two different BTH ligands in a {ZnO(2)N(2)} coordination environment. The three-dimensional topology of the title compound corresponds to that of a fivefold interpenetrating diamond-like metal-organic framework.
