An efficient way to generate a series of rigid tetrahedral organic building units from common methane and adamantane precursors is presented. Suzuki-Miyaura and Sonogashira cross-coupling reactions are used to effectively generate these shape-persistent molecular tectons. Especially the Sonogashira reactions employing the readily available tetrahedral alkynes and commercial iodides and bromides are

The synthesis of two novel tetrakis(salicylaldehydes) based on a rigid tetraphenylmethane core is presented. These salicylaldehydes were used as precursors for the construction of three-dimensional multimetallic salphens, as exemplified by the synthesis of rigid and shape-persistent tetranuclearzinc–, nickel– and palladium–salphens with defined geometries and distances between the metal sites. The
