| Synthesis and crystal structures of carboxylate clusters containing multiple manganese ions and aza ligands are described. Using the principles of crystal engineering a family of trigonal manganese clusters (TMCs) is designed with potential as nonlinear optical materials. These TMCs contain three Mn ions, six carboxylate and three aza ligands, and their structures fall into two distinct series, both of which contain two-dimensional noncentrosymmetric networks. Substitutional variation on benzoate and pyridyl ligands led to the predictable synthesis of a group of three-dimensional acentric solids. The crystal structures of TMCs are built on 36 and 44 networks, which are sustained by p-stacking interactions and C–H…O hydrogen bonds. Slight modifications in the synthetic procedures resulted in clusters of higher nuclearity and clusters containing six and thirteen Mn ions are identified. Current work involves the exploration of these multinuclear structures toward applications in magnetic and porous materials. |
