✦ Synopsis
Two novel microporous coordination polymers constructed by ladder-like and ribbon-like molecules with cavities:
(2) are obtained through assemble of the corner ligand and the metal Zn 2þ ion. The metal Zn 2þ ion of the coordination polymer (1) is in trigonal bipyramid environment: two O atoms from carboxyl groups and one N atom furnishing the equatorial plane and the other two O atoms in axes sites. For coordination polymer (2), the metal Zn 2þ ion center is in tetrahedron environment: three O atoms from carboxyl groups in bottom plane and another O atom from coordination water in axis site. These infinite ladder-like or ribbon-like molecules are orderly arranged to furnish hydrophilic microporous by molecular interaction and hydrogen bonds from water molecules and carboxyl groups. And their properties are studied in this paper.
