The word 'Unglück' is the direct opposite of 'das Glück' (luck/happiness). The prefix 'un-' negates the base word and can refer both to 'Glück haben' (to be lucky) as bad luck and to 'glücklich sein' (to be happy) as sorrow.
Er hatte das Unglück, seinen Zug zu verpassen.
He had the misfortune of missing his train.
When 'Unglück' means a countable event such as an accident, it can appear in the plural and have an article. If it refers to the general state of bad luck or sorrow, it is usually uncountable and used without an article.

The news reported a serious accident.
When 'Unglück' describes an event, it is often used with the verbs 'geschehen' (to happen) or 'passieren' (to happen). People also speak of the 'Unglücksort' (accident site) or say that an accident 'Opfer fordert' (claims victims).
Das Unglück geschah am frühen Morgen auf der Autobahn.
The accident happened early in the morning on the highway.
There are well-known proverbs with 'Unglück'. 'Ein Unglück kommt selten allein' means that several bad things often happen in quick succession.

First he lost his job, and then his car was stolen. Misfortunes never come singly.
