Syntheses and Crystal Structures of Ten Transition Metal Complexes with Di-Schiff Base and Mono-Schiff Base Derived from Salicylaldehyde and 1,2-Diaminepropane

Ten metal complexes,MnL].H2O(1),CuL].H2O(2),Cu4L2Cl4](3),Mn4L2Cl4](4),CrL(H2O)2](NO3)(5),Cd2L'2(CH3OH)2(NO3)2](6),NiL]3(sal).2H2O(7),CoL(H2O)2]2.4H2O(8),CoL'2](CIO4)(9)and(UO2)L(CH3OH)]2(10)have been prepared,where sal=salicylaldehyde,and the di-Schiff base H2L and the mono-Schiff base HL' were respectively from the(2+1)and(1+1)condensations of salic ylaldehyde with 1,2-diaminepropane.The ten complexes have been characterized by elemental analyses and single-crystal X-ray diffraction,which reveals that complexes 1-10 as a series,although being synthe sized by the similar methods,are varied in structure geometry.
