Deca­chloro­cyclo­penta­silanes coordinated by pairs of chloride anions, with different cations, but the same solvent mol­ecules

We have determined the crystal structures of two deca­chloro­cyclo­penta­silanes, namely bis­(tetra-n-butyl­ammonium) dichloride deca­chloro­cyclo­penta­silane di­chloro­methane disolvate, 2C16H36N+·2Cl−·Si5Cl10·2CH2Cl2,
We have determined the crystal structures of two deca­chloro­cyclo­penta­silanes, namely bis­(tetra-n-butyl­ammonium) dichloride deca­chloro­cyclo­penta­silane di­chloro­methane disolvate, 2C16H36N+·2Cl−·Si5Cl10·2CH2Cl2, (I), and bis­(tetra­ethyl­ammonium) dichloride deca­chloro­cyclo­penta­silane di­chloro­methane disolvate, 2C8H20N+·2Cl−·Si5Cl10·2CH2Cl2, (II), both of which crystallize with discrete cations, anions, and solvent mol­ecules. In (I), the complete deca­chloro­cyclo­penta­silane ring is generated by a crystallographic twofold rotation axis. In (II), one cation is located on a general position and the other two are disordered about centres of inversion. These are the first structures featuring the structural motif of a five-membered cyclo­penta­silane ring coordinated from both sides by a chloride ion. The extended structures of (I) and (II) feature numerous C—H⋯Cl inter­actions. In (II), the N atoms are located on centres of inversion and as a result, the ethyl­ene chains are disordered over equally occupied orientations.
