In this paper, 20 novel complexes with different metal salts were synthesized from semi-rigid tripod ligands (3n5bis (2-carboxyphenoxy) benzoic acid (H3BCPB) under solvothermal reaction conditions. X-ray single crystal diffraction analysis, IR analysis, elemental analysis, PXRD and TG analysis, fluorescence determination of complex 1t2, and determination of magnetic properties of the complexes 1O2O6C9ON10 and 11 have been carried out by X-ray single crystal diffraction analysis, IR analysis, elemental analysis, PXRD and TG analysis.
