Abstract: Synthesis and Crystal Structure of Li[{Ca 7 (µ 3 -OH) 8 I 6 (thf ) 12 } 2 (µ-I)]·3THF (IV), a Unique H-Bound Dimer of a Ca 7 -Cluster on the Way to Sol-Gels.-In analogy to transition metal clusters, the mixed ligand Ca-cluster compound (IV) is synthesized. (IV) consists of two neutral Ca 7 -cluster units linked together by a bridging iodide ion which forms hydrogen bonds to an OH-group of each Ca 7 -unit. The structure of the Ca 7 -subunit can be described as two (Ca-O) 4 heterocubanes sharing a Ca-corner. (I…
