Popis: The title complex, [{Os2(CO)4(C21H21P)2}2(C12H14O4)2], is a centrosymmetric molecular loop consisting of two Os—Os sawhorse units linked by two adamantane dicarboxylato bridges. It was synthesized by the microwave-mediated reaction between Os3(CO)12 and adamantane-1,3-dicarboxylic acid. In contrast to the related complex [{Os2(CO)6}2(μ4-adamantane-1,3-diacetate)2], the metal–metal axes within each molecule are oriented parallel rather than perpendicular to one another. The crystal structure exhibits cavities that contain residual electron density peaks, but it was not possible to unambiguously identify the solvent therein. The contribution of the disordered solvent molecules to the scattering was removed using the SQUEEZE (Spek (2015). Acta Cryst. C71, 9–18) routine in PLATON [Spek (2020). Acta Cryst. E76, 1–11]. These solvent molecules are not considered in the given chemical formula and other crystal data.
