Novel complexes of Pt2+, Pd2+ and UO2 2+ with N,N′-bis(2-pyridyl)thiourea (H2BPT) 1 were synthesized. These complexes namely [Pt(HBPT)2] 2, [Pd(HBPT) 2] 3 and [UO2(HBPT)(OAc)(H2O)] 4 , were characterized by elemental analysis and spectral measurements. Suggested structures (square-planar for both 2 and 3 complexes and pentagonal-bipyramidal geometry for 4) were confirmed by applying geometry optimization and conformational analysis. Thermal properties and decomposition kinetics of all compounds are investigated. The interpretation, mathematical analysis and evaluation of kinetic parameters (E, A, ΔH, ΔS and ΔG) of all thermal decomposition stages have been evaluated using Coats-Redfern, Horowitz-Metzger and MKN Methods: The biochemical studies showed that, complex 2 has powerful and complete degradation effect on DNA. The antibacterial screening demonstrated that, complex 2 has the maximum and broad range activities against Gram-positive and Gram-negative bacterial strains.

A highly efficient procedure for the synthesis of symmetrical thioureas by means of simple condensation of primary amines and carbon disulfide in 1-butyl-3-methylimidazolium chloride [BMIM][Cl] as a cheap and commercially available ionic liquid is presented. This procedure works for aromatic and aliphatic primary amines and give high to excellent yields of symmetrical thioureas without need for any catalyst or tedious work-up.
