Abstract
Methods for the synthesis were developed and new homo- and heterometallic cadmium ([Eu2Cd2(MeCN)4(C6F5COO)10] (I), [Tb2Cd2(MeCN)6(C6F5COO)10]·4MeCN (II)) and zinc ([Zn(H2O)(C6F5COO)2] (III), [Eu2Zn2(MeCN)4(C6F5COO)10] (IV)) complexes were characterized. These complexes can be used as precursors for the synthesis of compounds with N-donor ligands. Complexes I and II differ in the coordination of the MeCN molecule, which is coordinated in II by each Tb3+ ion. Also, additional coordination of MeCN induces a greater distortion of the {Tb2Cd2} metal core of II. The crystal packing in I–IV is stabilized by numerous intermolecular O…H, F…F, C–H…F, and C–H…O contacts. The new compounds were characterized by single crystal X-ray diffraction (CCDC no. 2076524 (I), 2082731 (II), 2082803 (III), 2076525 (IV)), IR spectroscopy, C,H,N elemental analysis, and powder X-ray diffraction.
