SYNTHESIS AND CRYSTAL STRUCTURE OF PENTANUCLEAR HETEROMETALLIC Pd(II)-La(III) ACETATE COMPLEX

摘要

The structure of a novel pentanuclear heterometallic complex Pd3La2(OOCMe)(12)(MeCOOH)(4) with an unusual ratio of metals 3Pd:2La is studied by XRD. The complex is prepared by the reaction of palladium acetate Pd-3(OOCMe)(6) with lanthanum acetate La(OOCMe)(3)center dot 1.5H(2)O. The molecule of the complex contains two heterometallic binuclear fragments PdLa(OOCMe)(5)(MeCOOH)(2) connected to the structure-forming fragment Pd(OOCMe)(2) via bridging acetate groups and hydrogen bonds of coordinated acetic acid.
