Two Schiff base zinc(II) complexes, [ZnBr2L1] center dot 2CH(3)OH (I) (I) and [ZnBr2L2] (II), where L-1 is 4-chloro-2-[(2-piperazin-1-ylethylimino)methyl]phenol and L-2 is 4-chloro-2-[(3-diethylaminopropylimino)methyl]phenol were synthesized and structurally characterized. The crystal of I is monoclinic: space group P2(1)/c, a = 9.831(3), b = 18.680(6), c = 11.879(4) , beta = 94.660(6)A degrees, V = 2174.3(11) (3), Z = 4. The crystal of II is monoclinic: space group P2(1)/n, a = 7.2310(14), b = 16.037(3), c = 15.856(3), beta = 90.01(3)A degrees, V = 1838.7(6) (3), Z = 4. The Zn atom in each complex is four-coordinated by one phenolate O and one imine N atoms of the Schiff base ligand and two bromide atoms, forming a tetrahedral coordination. The urease inhibitory activities of the complexes were evaluated.
