Figure 2
Representation of the four-membered Sn2O2 ring showing the most important bond angles (°) and bond lengths (Å). Positions of the oxygen and chlorine atoms within the trigonal–bipyramidal coordination of the tin atoms are labeled by use of the abbreviations ax (= axial) and eq (= equatorial). For clarity, Ph groups are stripped down to the Sn—C bonds drawn as shortened sticks. |
