reaction of two sterically different bithiazole ligands with gold(III) was investigated. Our results show that, depending on the ligand used, different coordination geometries around the gold(III) center were achieved. Where sterically unhindered 4bt ligand was used, regular square-planar compound [Au(4bt)Cl2][AuCl4] (1) is isolated, while in the case of sterically hindered dm4bt ligand, the interplay
