    A new and versatile class of metalā€“organic materials (MOMs) with augmented lonsdaleite-e (<b>lon-e</b>-a) topology is presented herein. This family of <b>lon-e</b> nets are built by pillaring of hexagonal two-dimensional kagomeĢ (<b>kag</b>) lattices constructed from well-known [Zn<sub>2</sub>(CO<sub>2</sub>R)<sub>4</sub>] paddlewheel molecular building blocks (MBBs) connected by 1,3-benzenedicarboxylate (bdc<sup>2ā€“</sup>) linkers. The pillars are [Cr<sub>3</sub>(Ī¼<sub>3</sub>-O)Ā­(RCO<sub>2</sub>)]<sub>6</sub> trigonal prismatic primary MBBs decorated by six pyridyl moieties (tp-PMBB-1). The three-fold symmetry (<i>D</i><sub>3<i>h</i></sub>) of tp-PMBB-1 is complementary with the alternating orientation of the axial sites of the paddlewheel MBBs and enables triple cross-linking of the <b>kag</b> layers by each pillar. These MOMs represent the first examples of axial-to-axial pillared undulating <b>kag</b> layers, and they are readily fine-tuned because the bdc<sup>2ā€“</sup> moieties can be varied at their 5-position without changing the overall structure. This <b>lon-e</b> platform possesses functionalized hexagonal channels since the <b>kag</b> lattices are necessarily eclipsed. The effects of the substituent at the 5-positions of the bdc<sup>2ā€“</sup> linkers upon gas adsorption, particularly the heats of adsorption of carbon dioxide and methane, were studied
