Abstract
Two new 3-D supramolecular compouds: [Cu2X2(Hpyba)2]n (X = Br (1), I (2), Hpyba = 4-pyridin-4-yl-benzoic acid) have been hydrothermally synthesized and structurally characterized. Although both compounds exhibit different space groups, they have a similar structure. Each {Cu2X2} cluster unit interconnects to form a 1D stair-step chain. The Saturated Hpyba ligands are regularly appended to both sides of main chain, linked via N atoms of ligands. These infinite chains are further linked by H-bonds and π–π interactions to form a 3-D supramolecular network structure. The thermal stability of 1 and 2 was investigated by thermogravimetric measurements.
Graphical Abstract
Two new 3-D supramolecular compouds [Cu2X2(Hpyba)2]n (X = Br(1), I(2), Hpyba = 4-pyridin-4-yl-benzoic acid) have been obtained under hydrothermal conditions. Both compounds exhibit a 1D stair-step chain structure based on the {Cu2X2} cluster units. These infinite chains are further linked by H-bonds and π–π interactions into forming a 3-D supramolecular network with two types of channels along different directions.
