Two in one: a facile modular approach for the assembly of pnictogen-rich heteroleptic organometallic complexes
The reactions between soluble 1D polymer [Ag{(η<sup>2</sup>:η<sup>1</sup>-A)}<sub>2</sub>] <sub><i>n</i></sub> [TEF] <sub><i>n</i></sub> , obtained from five-fold symmetric building blocks [Cp*Fe(η<sup>5</sup>-P<sub>5</sub>)] (A, Cp* = η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>) and a weakly coordinating salt of Ag(i), and a series of ditopic-tetrahedral organometallic building blocks, [{CpMo(CO)<sub>2</sub>}<sub>2</sub>(η<sup>2</sup>-E<sub>2</sub>)] (E = P, As) or [{CpMo(CO)<sub>2</sub>}<sub>2</sub>(η<sup>2</sup>-PE)] (E = As, Sb), have been investigated. It is shown that, depending on the choice of the ditopic-tetrahedral complexes, a rational design of unprecedented heteroleptic 1D polymer or discrete molecular systems containing two different pnictogenyl building blocks is possible. Weak π-π interactions, adaptive coordination behavior of the Ag(i), argentophilic interactions and the fine-tuned electronic properties of the ditopic-tetrahedral complexes directed the product formation. The modular synthetic approach paves the way for hybrid systems containing heteroleptic pnictogen-rich supramolecular assemblies.
