Figure 2
Displacement ellipsoid plot of the centrosymmetric four-membered tin–oxygen ring of the [EtSnBr2(OH)·DMF]2 molecule, highlighting selected bond lengths (Å), angles (°) and distances (Å) from the Sn–O reference plane in square brackets. With the exception of the H atoms, which are shown as spheres of arbitrary radius, all other atoms are drawn with displacement ellipsoids at the 40% probability level. For clarity, ethyl groups are stripped down to the Sn—C bonds drawn as shortened sticks. Intermolecular O—H⋯Br hydrogen bonds are indicated as dashed sticks in brown. Descriptors trans and cis refer to the position of the corresponding bonds with respect to the tin–carbon bond of the ethyl group. |
