Heterocyclic compounds of the formula:
wherein either X is -CR1R2- and Y is -0-, -S- or -NHR3-, wherein R1, R2 and R3, which may be the same or different, each is hydrogen or alkyl of up to 4 carbon atoms; or X is -0-, -S- or -NH- and Y is -CR1R2- wherein R1 and R2 have the meanings stated above; wherein R4 and R5, which may be the same or different, each is hydrogen (but provided that R4 and R5 are not both hydrogen), or each is a group defined in claim 1 which is readily convertible into a carboxy group; processes for their manufacture; and pharmaceutical compositions containing them. The compounds possess cardiotonic and/or antihypertensive activity.
