Syntheses and Crystal Structures of Ten Transition Metal Com plexes 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(H2 O)2](NO3)(5),[Cd2L'2(CH3OH)2(NO3)2](6),[NiL]3(sal).2H2O(7),[CoL(H2O)2]2.4H2O(8),[CoL'2](ClO 4)(9) and [(UO2)L(CH3OH)]2(10) have been prepared,where sal = salicylaldehyde,and the di-Schiff bas e 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.
