An unprecedented ι-type octamolybdate: [TbI1]2[(β-Mo8O26)0.5(ι-Mo8O26)] directed by a new tricationic template†
Abstract
Trication-templated assembly of POMs resulted in an unprecedented ι-type octamolybdate configuration. The ι-[Mo8O26]4− cluster is composed of five {MoO6} octahedra and three {MoO4} tetrahedra via an edge-sharing and corner-sharing arrangement to form a cabas-like cluster, which represents the ninth isomer of octamolybdates.
