They were first found in the 1940s, but their discovery went unnoticed until recently. Interesting find, up until now MOFs were only made in lab.

"NaMgAl(ox)3·9H2O was prepared according to a published procedure (22). Synthetic stepanovite was prepared by dissolving stoichiometric amounts of
NaOH, MgO (≥99% trace metals basis, ~325-mesh powder; Sigma-Aldrich), and Fe2O3 (nanopowder; Sigma-Aldrich) in aqueous oxalic acid solution. The
resulting green solution was stirred overnight, filtered, and left to evaporate at 4°C. Green, rhombohedral crystals were obtained after 2 days."
