Cyclic trinuclear copper(I) and silver(I) complexes (CTCs) with anionic pyrazolate ligands form a wide class of compounds with a planar structure. These complexes exhibit a variety of coordination chemistry, and their planar structure leads to metalophilic interactions in the solid state, determining their photophysical behavior through the formation of excimers. As Lewis acids, these compounds can form noncovalent intermolecular complexes with various bases. This opens up opportunities for designing new aggregates with predictable structures and properties. One popular strategy for creating new coordination compounds involves intermolecular forces, such as metal-metal or metal-π interactions.1-4 On the other hand, the use of P- or N-containing ligands can lead to the rearrangement of the metal-pyrazolate core, opening up new possibilities for noncovalent complexes formation. The talk covers our findings on the investigation of the intermolecular interactions between trinuclear pyrazolate complexes and bases of various types and structures. References 1. A. A. Titov, O.
