Abstract

Abstract : A new neutral host Pd2 L2 metallacycle, featuring a bulky bis[3‐pyridyl(hydroxy)methyl]‐1, 2‐dicarba‐ closo ‐dodecaborane, is synthesized, and seven crystalline inclusion compounds are obtained from DMF, DMSO, EtOAc, and THF, with the last four acting as guest solvents. Single‐crystal X‐ray diffraction structural analysis shows the formation of 1: n ( n = 6–8) host/guest crystals, indicating a high stoichiometric ratio of included solvent. Single‐crystal X‐ray diffraction analyses of all structures reveal a supramolecular ordering of the palladacycles in the solid state, through extensive hydrogen bonding or intermolecular contacts, mainly between the host and the guest molecules. Abstract : A new neutral host Pd2 L2 metallacycle, featuring a bulky bis[3‐pyridyl(hydroxy)methyl]‐1, 2‐dicarba‐ closo ‐dodecaborane, acts as a host for seven crystalline inclusion compounds from DMF, DMSO, EtOAc, and THF, in an exceptional ratio of host/guest 1: n ( n = 6–8).
