Abstract

A tetramer cluster complex of the formula [Pr4Cl10(OH)2(thz)8(H2O)2] was prepared constituted by two edge sharing metal triangles coordinated by thiazole (thz) and chloride ligands bent together by opposing μ3-hydroxide and chloride capping for both triangles. The tetramer is the first thiazole complex of a lanthanide ion and shows a previously unknown symmetric capping mode. It co-crystallizes with an anhydrous dimeric complex of the formula [Pr2Cl6(thz)8] in equal amounts.
