A series of bis(pyridyl)-bis(amide)-modulated metal-1,2-phenylenediacetate coordination polymers: construction and selective dye adsorption

Abstract

Five new coordination polymers (CPs), namely, [Cu(3-bpcb)(1,2-pda)]·2H2O (1), [Cu(4-bpah)(1,2-pda)(H2O)]·H2O (2), [Ni2(4-bpah)2(1,2-pda)22-H2O)] (3), [Cu3(4-bpfp)(1,2-pda)23-OH)2] (4), [Co(4-bpfp)0.5(1,2-pda)(H2O)] (5), were prepared by hydrothermal reactions of metal(II) chloride with 1,2-H2pda (H2pda = 1,2-phenylenediacetic acid) in the presence of different bis(pyridyl)-bis(amide) ligands (3-bpcb = N,N′-bis(3-pyridinecarboxamide)-1,4-benzene; 4-bpah = N,N′-bis(4-pyridinecarboxamide)-1,2-cyclohexane; and 4-bpfp = N,N′-bis(4-pyridylformyl)piperazine) and structurally characterized by single crystal X-ray diffraction, infrared spectroscopy (IR), elemental analysis, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). Complexes 1–3 show three different 2D layers with diverse (42·67·8)(42·6), (44·62) and (42·6)(42·67·8) topological structures, respectively. Complex 4 exhibits a 3D polymeric framework, which presents a novel (3,4,8)-connected topology with the Schläfli symbol (3·4·5)2(32·42·52·614·74·83·9)(32·63·7). Complex 5 displays a 3D network with 3,4-connected (42·63·8)(42·6) topology. The diverse arrangements of these complexes show the remarkable sensitivity of the metal(II)–H2pda system to the different bis(pyridyl)-bis(amide) ligands. In addition, the electrochemical properties of complexes 3–5 and the dye adsorption properties of the title complexes are also discussed.
