Syntheses,Structures and Anticancer Activities of Three 4(3H)-Quinazolinone Cd(Ⅱ) Complexes

The title complexes based on 4(3H)-quinazolinone ligand have been synthesized and characterized by elemental analysis, IR spectrum and single-crystal X-ray diffraction analysis.Complex 1 belongs to the triclinic system, space group P1, with a = 6.5392(3), b = 7.4402(5), c =10.3397(7) ?, α = 83.204(5), β = 75.465(5), γ = 86.075(5)° and V = 483.88(5) ?~3. Complex 2 is of orthorhombic system, space group Pbca, with a = 10.1294(3), b = 7.6747(5), c = 23.8171(15) ? and V = 1849.1(4) ?~3. Complex 3 belongs to the orthorhombic system, space group Pbca, with a =12.7188(2), b = 6.66582(9), c = 25.6987(6) ? and V = 2178.77(5) ?~3. The complex structures are affected by the synthesis conditions.
