I always thought that Zwischenzug referred to the situation where the player about to move has all his / her pieces tied up protecting things but, because it is their move, the position is ruined because the only moves available seriously weaken the position. But, my latests Chess books define it differently viz: making a move to sort out a minor threat whilst a more important threat is challenged by the next move.
What is Zwiscenzug and what is the name of the situation I have referred to above>

You mean zugzwang, compulsion to move. Zwischenzug is the in-between move between a capture and re-capture.

Zwischenzug
A German term for an 'in-between' move. Instead of making the obvious move, like an immediate recapture, a player interposes a move to achieve a favorable objective.
