In the course of work on main-group silyl compounds, crystals of the title compound, [Hg(C3H9Si)2]2, were prepared. An earlier X-ray analysis of this compound failed to give a full structural characterization. Here, the title compound is found to consist of dimers with 222 crystallographic symmetry formed by two molecules of (Me3Si)2Hg linked by a weak Hg
Hg interaction with an interatomic distance of 3.1463 (6) Å. Each Si—Hg—Si frame is nearly linear and has an Hg—Si distance of 2.4913 (18) Å.

The title compound, [GaCl2(C3H10NSi)(C4H8O)], is the tetrahydrofuran-coordinated monomer of the previously structurally characterized dimer [GaN(H)SiMe3Cl2]2. The title compound consists of discrete monomeric molecules with two crystallographically independent molecules within the unit cell. The crystal structure is composed of a Ga atom in a four-coordinate tetrahedral arrangement, with Ga-N distances of 2.025 (3) and 2.026 (3) Å in the two independent molecules.
