Two-dimensional coordination polymers based on pyridine-containing cations of cu(II) and Ni(II) and 1,3,5-benzenetricarboxylate anion and their supramolecular structure

New coordination compounds based on 1,3,5-benzenetricarboxylate (btc 3− ) and complex cations of copper(II) and nickel(II) with monodentate ligands {{[Cu(py) 3 ] 3 (btc) 2 }·4,5H 2 O} n ( 1 ) and {[Ni(py) 3 (H 2 O)] 3 (btc) 2 } n ( 2 ) were obtained. The molecular and crystal structures of these com...

Description
Summary:New coordination compounds based on 1,3,5-benzenetricarboxylate (btc 3− ) and complex cations of copper(II) and nickel(II) with monodentate ligands {{[Cu(py) 3 ] 3 (btc) 2 }·4,5H 2 O} n ( 1 ) and {[Ni(py) 3 (H 2 O)] 3 (btc) 2 } n ( 2 ) were obtained. The molecular and crystal structures of these compounds and their isomorphism were determined by X-ray diffraction analysis. Crystals of 1 and 2 are characterized by a layered structure due to the stacking of two-dimensional coordination-polymer layers interacting with each other through C-H…π non-covalent interactions and C-H…O weak hydrogen bonds. It is shown that these compounds are potentially highly porous materials with coordinatively unsaturated metal ions (Lewis acid sites).
