The Titanium complexes stand for a new category of potential anticancer compound. The first studies of titanium complexes copied square-planar arrangement of cis-platin complexes. These complexes show a significant anticancer activity for a wide range of cell lines of cancer . We synthesized new titanium complexes derived from salicylic acid derivatives (as 3-methoxysalicylic acid) and N,N-bidentate ligands (as 1,10-phenanthroline) or monodentate O, N,-ligands (as imidazole) . These complexes were prepared in monocrystal form and suitable crystals were selected for X-ray experiment. All experiments were performed by Stoe STADIVARI diffractometer with a Dectris Pilatus 300 K detector and with an Genix3D Cu HF source (Cu-Kα, λ = 1.54186 Å) at 100 K using a nitrogen gas open-flow cooler Cobra Oxford Cryosystems. Data reduction was performed using X-Area (Stoe, 2017) software package . The crystal structures for measured compounds were solved in OLEX2 software using SHELXT-2015 program via Intrinsic Phasing and refined with SHELXL-2014 by least-squares procedure on F2. Since few efforts have been made towards the synthesis and use of titanium complexes as chemotherapeutic agents, this is an important area of our research.
