Sequential transformations in assemblies based on octamolybdate clusters and 1,2-bis(4-pyridyl)ethane†‡
Abstract
The new hybrid inorganic–organic solids [Mo8O26][H2bpe]2 (1), {[Mo8O26(μ-bpe)][H2bpe]2}n (2), [Mo8O26(Hbpe)2][H2bpe] (3), and {[Mo8O26][H2bpe]2}n (4) were synthesized under hydrothermal conditions. The crystal structure of 1 contains the discrete octamolybdate β-isomer, whereas in 3 the inorganic building unit is a functionalized octamolybdate of general formula [Mo8O26X2](2n+4). A similar building unit is found in 2 and 4, but forming part of polymeric 1D-arrays. In 2 the
