摘要

A series of psychotropic heterobicycloalkylpiperazine derivatives having the structure ##STR1## wherein V is a 3- or 4-membered unsaturated chain, containing all carbon atoms when 4-membered, or when a 3-membered chain, V contains an oxygen or sulfur atom as one of the members; R is H or C.sub.1-4 alkyl; W is CH, N, CH.sub.2, or a chemical bond; X is CH, N, SO.sub.2, or CO, with the proviso that both W and X cannot simultaneously be N; and Z is a heteroaromatic ring system. These compounds are useful antipsychotic and/or anxiolytic agents.
