1D, 2D and 3D coordination polymers of 1,3-phenylene diisonicotinate with Cu(i)/Cu(ii): Cu2I2 building block, anion influence and guest inclusions

Abstract

The reactions of a flexible bidentate ligand 1,3-phenylene diisonicotinate (L) with Cu(I/II) salts afforded coordination polymers with varied dimensionalities and guest inclusion capabilities. Complexation of L with CuI resulted in a 2D-network with (4,4) topology and inclusion of guest molecules such as CHCl₃, bromobenzene, nitrobenzene and benzonitrile. The treatment of L with Cu(PF₆)₂ and Cu(ClO₄)₂ resulted in a one-dimensional network containing M₂L₂ macrocycles and a 4-fold interpenetrated three dimensional network having quartz topology, respectively. The 1D-networks included CHCl₃ as guests and the interpenetrated 3D-network includes tetrahedral water clusters.
