The molecule is centered on a piperazine ring, a saturated six-membered heterocycle with two nitrogens positioned opposite each other. Each piperazine nitrogen is acylated, linking out through a carbonyl group (-C(=O)-) to a different aromatic ring.

- One acyl linker terminates in a pyridine ring (six-membered aromatic with one ring nitrogen). The pyridine attachment point is ortho to the ring nitrogen. On this pyridine, the carbon ortho to the ring nitrogen and the carbon para to the ring nitrogen each bear a chlorine atom.

- The other acyl linker terminates in a thiophene ring (five-membered aromatic ring with one sulfur). The attachment is at the carbon ortho to the sulfur (the 2-position of thiophene).
