| description | Despite that the chemistry of octahedral cluster complexes has been actively developed recently, there are still a lot of unexplored areas. For example, to date, only a few halide M<sub>6</sub>-clusters with N-heterocycles are known. Here, we obtained an apically heteroleptic octahedral iodide molybdenum cluster complex with pyridine ligands—<i>trans</i>-[{Mo<sub>6</sub>I<sub>8</sub>}(py)<sub>2</sub>I<sub>4</sub>] by the direct substitution of iodide apical ligands of [{Mo<sub>6</sub>I<sub>8</sub>}I<sub>6</sub>]<sup>2–</sup> in a pyridine solution. The compound co-crystalized with a monosubstituted form [{Mo<sub>6</sub>I<sub>8</sub>}(py)I<sub>5</sub>]<sup>–</sup> in the ratio of 1:4, and thus, can be described by the formula (pyH)<sub>0.2</sub>[{Mo<sub>6</sub>I<sub>8</sub>}(py)<sub>1.8</sub>I<sub>4.2</sub>]·1.8py. The composition was studied using XRPD, elemental analyses, and <sup>1</sup>H-NMR and IR spectroscopies. According to the absorption and luminescence data, the partial substitution of apical ligands weakly affects optical properties. |
