A 3-D porous Ni^II coordination polymer constructed from oxalate and hydrazine linkers

Abstract

A Ni^II-MOF, {[Ni(C₂O₄)(N₂H₄)]·2H₂O}_n (1), was constructed by oxalate and hydrazine under hydrothermal conditions at 130 °C. Single-crystal X-ray structural analysis indicates that 1 has a 3-D porous architecture with (10³) topology based on two kinds of 1-D zigzag [Ni(C₂O₄)]_n chains with the same structure but different extension directions in the ab plane separated by N₂H₄ linker. 1 reveals antiferromagnetic behavior and thermal stability below 283 °C.
