Complexity is the state of having many parts and being difficult to understand: the complexity of the rules, a problem of some complexity. Difficulty is everyday and broader; complication is a problem that makes things harder, not the structure itself. Complex is the adjective. In speech, how complicated it is is enough. Complexity can be necessary (a legal system); do not use it as a compliment for muddy writing.
