The molecule has a piperazine backbone, a saturated six-membered ring with two nitrogen atoms in opposite positions. Each nitrogen is substituted:

Only the two nitrogens are substituted in this piperazine:

1. First nitrogen: bonded through a carbonyl bridge (-C(=O)-) to a cyclopropane ring (a saturated three-carbon ring). On this cyclopropane, one of the non-bridge carbons bears an isopropyl group (-CH(CH3)2).
2. Second nitrogen: bonded through another carbonyl bridge (-C(=O)-) to a methylene group (-CH2-), which is attached to a para-chlorophenyl ring. The entire substituent can be described as -C(=O)-CH2-C6H4-Cl (para).
