Gold(III) porphyrinates have been extensively studied due to their high stability and anticancer activity. Fewer attention has been paid to structural features of such compounds. In this work, a new gold(III) complex [Au(TBPP)][AuCl4] (1) was synthesized in high yield starting from 5,10,15,20-tetrakis-(4-butoxyphenyl)porphyrin (TBPPH2). The compound was characterized by IR, 1H NMR and UV-vis spectroscopies, ESI-MS, cyclic voltammetry and elemental CHN analysis. The crystal structure of 1 was determined using X-ray diffraction analysis. Crystalline phases [Au(TBPP)]2[AuCl4][AuCl2]*2НOAc (1a) and [Au(TBPP)]2[AuCl4][AuCl2] (1b) were also isolated. Analysis of all three crystal structures revealed the tendency of the [Au(TBPP)]+ cationic complex to form weak intermolecular Au⋯Au, Au⋯Cl, Au⋯O interactions with [AuCl4]- anions, HOAc molecules, and neighboring [Au(TBPP)]+ cations. DFT calculations at ωB97XD/DZP-DKH level of theory confirmed the non-covalent nature of these interactions.
