Rapid and Simple Isolation of the Crystalline Molybdenum‐Blue Compounds with Discrete and Linked Nanosized Ring‐Shaped Anions: Na ₁₅ [MoMoO ₄₆₂ H ₁₄ (H ₂ O) ₇₀ ] _0.5 [MoMoO ₄₅₇ H ₁₄ (H ₂ O)

An Unstable Paramagnetic Isopolyoxomolybdate Intermediate Non‐Homogeneously Reduced at Different Sites and Trapped in a Host Based on Chemical Adaptability

“…However, in case of compound 1 we have to consider its more complicated chain construction (Figure S2) as well as the presence of three {Mo 2 }‐type defects (see formula and Figure 1), two of which are necessary for the mentioned cluster trapping (see below). It should be noted that a type of chain compound exists also without trapped {Mo 36 } clusters 8. But whereas in the latter compound, linking occurs through four Mo‐O‐Mo bonds,8 the ring segments of 1 are linked by five groups (see also Ref.…”

A Nanosized Molybdenum Oxide Wheel with a Unique Electronic‐Necklace Structure: STM Study with Submolecular Resolution

“…The studied compound contains 50 % of the wheels with x =1 (see Refs. 14a, 20, 21 as well as Experimental Section). a) Ball and stick representation of the wheel and side‐views of three of the 14 {Mo V/VI 5 O 6 } double cubane‐type compartments (yellow) in which, according to bond valence sum calculations, practically all of the 4d electron density occurs14a, 20 ({Mo V/VI 1 } units of the wheel as well as the corresponding Mo atoms (enlarged) in the compartments in yellow; O red; other Mo blue).…”

Photochemical Formation of Tire-Shaped Molybdenum Blues: Topology of a Defect Anion, [Mo142O432H28(H2O)58]12−

“…Compound 1 a as a discrete anion is a defect species derived formally by removing six sets of [Mo(H 2 O)O 2 ( μ ‐O)Mo(H 2 O)O 2 ] 2+ units ({Mo 2 }) for the construction of the inner rings from a hypothetical tire‐shaped cluster 2 , which consists of 140 MoO 6 octahedra and 14 MoO 7 pentagonal bipyramids, with approximately D 7d symmetry. The half‐deprotonated species {Mo 154 }, 2 a has been thermally isolated in the Na 2 MoO 4 ⋅2 H 2 O/Na 2 S 2 O 4 /HCl system, and the structure of 2 a has been described as a tetradecamer (with approximate D 7d symmetry) of a conjugated group consisting of three different building blocks as [{Mo 8 }+{Mo 2 }+{Mo 1 }]:4, 5 the {Mo 8 } unit is observed in a quarter moiety of {Mo 36 } and neighboring {Mo 8 } units above and below the equator of the ring are linked by a {Mo 1 } unit that lies in the equator (Figure 1 and 2). …”
