Two new hydrated monocationic Cu(II) complexes with 1,3-propylenediamine and 1,2-ethylenediamine of general formula [CuBr(N-N)·HO]Br were prepared. The complexes were identified by means of several spectroscopic tools (Uv-visible, IR and MS), thermally (TG/DTA) and CHN-elemental analysis. The three dimensional structure for complex A and B was provide by X-ray diffraction studies and showed the Cu(II) ion as 4 + 1 + 1 coordinated, four nitrogen atoms of the diamine ligands, one bromide ion and one HO semi-coordinated to the Cu(II) center, a typical trans effect is clearly observed in the two complexes. The molecular crystal structures are linked via several H-bonds like N_H…Br and N_H…O. Additionally, intra-molecular H-bonds of kind C_H…Br is observed; these interactions lead to crystal structure three dimensional architecture packing. Hirshfeld surfaces (HSA) analysis was served to figure out the inter-contacts and fingerprints atoms percentage. DNA-binding, antitumor and antibacterial effectiveness of the desired complexes were evaluated.

This work was presented as a master's thesis and defended by author ABO under the supervision of author SAB at Al-Quds University in collaboration with author MA who provided several bacterial strains and helped in their morphological and cultural identification. Author IW suggested several ideas on media formulation. Author IS performed the real time PCR using his resources. All authors read and approved the final manuscript.
