| Abstract: | trans‐Bis(3‐isopropyl‐7‐oxocyclohepta‐1,3,5‐trien‐1‐olato)copper(II) trans‐bis(3‐isopropyl‐7‐oxocyclohepta‐1,3,5‐trien‐1‐olato)palladium(II) as the (5/1) and (3/2) composites Cu(C10H11O2)2]·0.2Pd(C10H11O2)2] and Cu(C10H11O2)2]·0.67Pd(C10H11O2)2], respectively, where 3‐isopropyl‐7‐oxocyclohepta‐1,3,5‐trien‐1‐olate is the systematic name for the hinokitiolate anion (hino), are the first mixed‐metal cocrystalline products isolated from the Mx(hino)y family of complexes. These cocrystals contain square‐planar trans‐Cu(hino)2 and trans‐Pd(hino)2 molecules possessing crystallographic inversion symmetry. The bulk formulation for these cocrystalline compounds is Cu1?xPdx(hino)2, where x is 0.166 (4) for the (5/1) product and 0.399 (4) for the (3/2) product. This bulk formulation is simply a convenient average expression of the whole‐molecule substitutional disorder present in these compounds. The M—O bonds are in the range 1.9210 (11)–1.9453 (10) Å, the O—M—O bite angles are in the range 82.94 (4)–83.36 (4)°, and all of the hinokitiolate O atoms are involved in C—H...O hydrogen‐bonding interactions. |
