The molecule is mirror-symmetric, composed of three fused rings.

- At the center is a thiolane ring (a five-membered saturated heterocycle with one sulfur atom).

- On each side of the thiolane, a cyclohexane ring is fused, each sharing two adjacent carbons with the thiolane. This creates a symmetrical thiolane-bicyclohexane fusion system.

- In each cyclohexane, the carbon adjacent to the fusion junctions carries a methyl substituent.

- The overall structure is mirror-symmetric with respect to the central thiolane ring.
