•A 3-D ytterbium MOF was synthesized under hydrothermal condition.•Three independent Yb(III) atoms exhibit different coordination environments.•There are two different types of rod-shaped molecular building blocks in compound.•The one of rod-shaped MBB is composed of [YbO6] and [YbO6N2] polyhedrons.•The other of rod-shaped MBB is formed from [YbO7] polyhedrons.
A novel 3-D ytterbium metal–organic framework, [Yb4(AIP)6(2,2′-bipy)]n (1) has been synthesized by self-assembly of Yb(III) ions, 5-aminoisophthalic acid (H2AIP) and 2,2′-bipyridine (2,2′-bipy) under hydrothermal condition and characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction analysis. In compound 1, three crystallographically independent Yb(III) atoms adopt totally different coordination environments and are connected to each other by carboxylate groups to form two different kinds of rods: [(YbO6)(OCO)3(YbO6N2)]n and [(YbO7)(OCO)3(YbO7)]n, respectively. These rod-shaped molecular building blocks alternately are linked to each other through AIP ligands to form a 3-D framework with pcu-type rod packing arrangement. The thermal property and luminescent property of 1 have been investigated in the solid state.
