Intend (and hence intended) is a verb:

Intentional is an adjective, or (obsolete) noun:
intentional, adj. and n.
- Of or pertaining to intention or purpose; existing (only) in intention. intentional fallacy n. in literary criticism, the fallacy that the meaning or value of a work may be judged or defined in terms of the writer's intention.
- Done on purpose, resulting from intention; intended. Rarely of an agent: Acting with intention.
So, it would appear that if Bob killed the cat intentionally, Bob intended to kill that cat. This is called the 'Simple View', at least according to Michael Bratman.
In experiments though, this has not turned out to be the case in practice. One famous experiment (Knobe, 2003) presented people with a vignette in which a CEO, saying he didn't care about the environment, chose to make a profit knowing it would harm the environment. 82% 0f responses said he intentionally harmed the environment.
Changing the 'harm' to 'help', so the CEO said he didn't care about helping the environment, resulted in only 23% of respondents saying he intentionally helped the environment.
From this, it appears that intentionality depends to a large extent on whether the action is something to be condemned or praised, or in other words has an element of judgement in it.
This, basically, is your “intended and intentional action” reference.
