2,2-Dichloro-1,3-bis­(trimethyl­silyl)-1,3-diaza-2-silacyclo­penta­ne

In the title compound, C₈H₂₂Cl₂N₂Si₃, the central Si atom is tetra­hedrally coordinated by two Cl and two N atoms in a mol­ecule that has crystallographically imposed C₂ symmetry. Comparison is made with the isomorphous structure having titanium instead of silicon at the central position in the diaza­cyclo­pentane ring [Tinkler, Deeth, Duncalf & McCamley (1996). Chem. Commun. pp. 2623-2624].

4-[(2-Hydroxy­ethyl)­imino­meth­yl]-5-hydroxy­methyl-2-methyl­pyridin-3-ol

The title compound, C₁₀H₁₄N₂O₃, is a Schiff base which is derived from pyridoxal and represents, therefore, a vitamin B₆-related compound. Mol­ecules are linked into sheets by a combination of O—H...O and O—H...N hydrogen bonds.
