Two unsymmetrical, macrocyclic, heterodinuclear complexes, [(CuMII)-M-II(L)](ClO4)(2)center dot nH(2)O (n=3; M=Zn, Cd) have been obtained by cyclocondensation of N,N'-bis(3-rormyl-5-n-butylsalicylidene)ethylenediimine and 1,3-diaminopropane in the presence of M2+. The structures of both complexes were determined by X-ray diffraction techniques. In each complex, two metals are located in the tetraimine macrocyclic cavity, and a water molecule and a perchlorate group are separately coordinated to the metal ions on the same side of the ring. Coordination geometry around each metal is approximately square pyramidal. ESMS spectra were used to characterize the complexes and isotopic distributions were investigated.
