Hydrothermal and solution reactions of pyridine-2,6-dicarboxylic acid N-oxide (2,6-PDCO) and BaCl

O yield two metal–organic frameworks; namely [Ba(2,6-PDCO)]
n
(

) and [Ba(2,6-PDCO)·H

O]
n
(

), respectively. Single-crystal X-ray analyses reveal that compound
1
is a dense framework whereas compound
2
is a porous one, though both compounds have an infinite two-dimensional (2D) layer structure. Compounds
1
and
2
are the first examples of pyridine dicarboxylic acid N-oxide introduced into the alkaline earth metal–organic framework.
