The logically correct usage is to try to do something. The attempt is made for the purpose of, in order to do. It is not just a coincidence that one tries, and one does: the relationship between the attempt and the action is causal.
So AWE's recommended construction for formal English - and especially for academic purposes - is try to. Nevertheless, Fowler's Modern English Usage (1st and 2nd editions) can see nothing wrong with try and do something, which is very common in spoken English. By all means use it "when it comes natural" ([sic] Fowler, 1926). But don't be too natural when trying to produce the careful English that good academic writing demands.
It is a curiosity of English that this construction (~ and) only applies to the base form of the verb. One cannot say
trying and [verb]ing, or tried and [verb]ed, or s/he tries and gets home before dark - at least in the sense of s/he tries to get home before dark.
