Two coordination polymers constructed by 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2′-bipyridine: syntheses, structures and luminescence properties

Abstract

Coordination polymers (CPs) have attracted increasing interest in recent years. In this work, two new CPs, namely poly [[aquabis(2,2 0 -bipyridine-2 ] sesquihydrate], {[Mn(C 16 H 10 O 7 )(C 10 H 8 N 2 )]Á1.5H 2 O} n (2), have been prepared using the tricarboxylic acid 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2 0 -bipyridine under hydrothermal conditions. CP 1 displays a twodimensional layer structure which is further extended into a three-dimensional (3D) supramolecular structure via intermolecularinteractions, while CP 2 shows a different 3D supramolecular structure extended from one-dimensional ladder chains by intermolecularinteractions. In addition, the solid-state luminescence spectra of 1 and 2 were studied at room temperature.

A Scintillating One-Dimensional Coordination Polymer Based on Cadmium(II), N,N′-(1,4-Phenylenedicarbonyl)diglycinate, and 2,2′-Bipyridine: Crystal Structure, Hirshfeld Surface Analysis, and Luminescence Lifetime Properties †

“…Two crystallographic centers of inversion are located at the centroids of the doubly-bidentate and metal centers bridging N,N -(1,4-phenylenedicarbonyl)diglycinate ligands. The Cd-O distances ranges from 2.298 (5) to 2.574 (2) Å and the Cd-N distances are 2.328 (3) and 2.344 (3) Å. Distances and angles are in the expected ranges and comparable to those found in the literature [28][29][30][31][32]. Selected interatomic distances and angles are given in Table 2.…”
