Abstract

The interaction of a Pd(II) salt with macrocyclic ligand 1 containing thiophene-2,5-carboxamide and bipyrrole fragments is studied. It is demonstrated that only mono-palladium complex 2 is formed in the reaction of PdCl2(CH3CN)2 with ligand 1. Complex 2 was isolated as crystalline compound 2b additionally involving also triethylammonium acetate and solvent molecules. According to single crystal XRD data, the crystals of complex 2b have the composition of [C50H45N6O4PdS][C6H16N]+· 1/4(C5H12)·CH2Cl2, triclinic, space group \(P\bar 1\), a = 14.9608(5) Å, b = 17.5574(6) Å, c = 22.5893(8) Å, α = 75.218(5)°, β = 74.086(5)°, γ = 81.244(5)°, V = 5495.7(4) Å3, Z = 4 (two independent formula units), d calc = 1.375 g/cm3, μ = 0.526 mm−1. The central atom of palladium(II) is coordinated with amide, imine, pyrrole nitrogen atoms, and the oxygen atom of triethylammonium acetate.
