| Abstract: | Reaction of sodium perchlorate-crown ether derivative (LH2) complex Na2LH2](ClO4)2 (1) with palladium acetate afforded two related compounds of macrocyclic palladium(II)-sodium(I) dimeric tetranuclear complexes, Pd2Na2L2(mu-OH2)2](ClO4)2(CH2Cl2)3 (2) and Pd2Na2(L-)2](CH3CN)2(C3H6O)2 (3) and their structures were characterised by IR, NMR, mass and X-ray analysis; the latter was revealed as an unusual metal-mediated electron delocalised complex. |
