Enantiomeric 2,6-Dichlorospiro[3.3]heptanes

In the following structures carbon atoms are dark gray, hydrogens are cyan and chlorine is green. The molecules are initially shown as mirror images, and can be moved by clicking on the structure and dragging the mouse. Holding the shift key during this operation allows zooming. The stereo-prefix notation carries a subscript a to reflect the axial chirality. You should confirm the stereo-prefix assigned to each isomer by viewing from the end of the chiral axis.
Because the four-membered rings are slightly puckered (even more than shown here), the chiral axis is drawn for a conformational average.
