An Open Neodymium−Organic Framework with the NbO Structure Type Based on Binuclear SBU Involved In Situ Generated Formate

The solvothermal reaction of Nd(NO3)3·6H2O and 5-amino-2,4,6-triiodoisophthalic acid (H2atiip) in DMF/ethonal/H2O (5:2:1) in the presence of pyridine gave rise to a new open neodymium−organic framework having the NbO structure type, [Nd(HCOO)(atiip)(DMF)2]·DMF·H2O (1). Complex 1 can keep its diffraction pattern even after being heated to 200 °C.
