Abstract The results of the analysis of thermal stability for zinc (II) and boron (III) complexes with 3,3′,5,5′-tetramethyl-4-ethyl-4′-iodo-2,2-dipyrrin [HL 1 ], 3,3′-diamyl-4,4′-dimethyl-5,5′-dibromo-2,2′-dipyrrin [HL 2 ] and 3,3′,5,5′-tetramethyl-4,4′-dibromo-2,2′-dipyrrin [HL 3 ] of the composition [Zn(L 1 ) 2 ]–[Zn(L 3 ) 2 ] and [BF 2 L 1 ]–[BF 2 L 3 ] are presented. The influence of halogenation
