A new cyanoscorpionate - tris(4-cyano-3,5-diphenylpyrazolyl)borate (TpPh2,4CN) has been synthesized and characterized. The thallium complex of this ligand TlTpPh2,4CN has also been prepared and characterized by FT-IR, 1H NMR, and single-crystal X-ray-diffraction. The complex TlTpPh2,4CN crystalized in the monoclinic space group C2/c with unit cell a = 14.6697(10) Å, b = 13.9493(10) Å, c = 19.3347(12) Å, and b= 91.761(2)°. Structural comparison of TlTpPh2,4CN with analogous complexes demonstrated the effects of both steric and electron-withdrawing substituents on coordination geometry and the electronic properties of the metal ion. There were short contacts between the cyano groups and neighboring thallium ions that also indicated the ligand’s potential to form coordination polymers.
