摘要：
Two novel cerium (III) complexes, complex 1, [Ce(phen)(2)(SCN)(4)](PhenH) and complex 2, [Ce(phen)(2)(NO3) (SCN)(2)(CH3OH)] were synthesized and structurally characterized using conventional methods and single crystal X-ray diffraction. Spectroscopic studies on the binding of Hen Egg White Lysozyme (HEWL) protein with complexes 1 and 2 suggest that the value of binding constants K-b, for complex 1 and 2 are 5.6 x 10(5) M-1 and 9.6 x 10(5) M-1 respectively. Both the complexes were tested for protease activity with HEWL. The assessment of it by gel electrophoresis studies confirms the protease activity of both complexes.
