A novel porous coordination polymer based on rigid and flexible organic ligands

A novel bilayered coordination polymer with nanoporous channels [Ni3(bix)3(PTCO)2 (H2O)4·6H2O]n (1) has been synthesized and the permanent porosity of (1) is confirmed by N2 adsorption isotherm measurement.

Graphical abstractA novel porous bilayered coordination polymer has been successfully synthesized, and its structures were determined by single-crystal X-ray diffraction studies. By topological approach, the whole structure is a unprecedented 3,4,4-connected network with a Schäfli symbol of (63)2(64·82)2(65·10). PXRD and TGA indicate it is a rare example of a MOF with the framework being sustained after the removal of the guest molecules.Figure optionsDownload full-size imageDownload as PowerPoint slide
