A vicinal dihalide.

Vicinal means "neighboring" or "adjacent", and, well, dihalide means there are two halogenic atoms on those adjacent carbon atoms. An example is 2,3-dibromobutane.

(On the other hand, a geminal dihalide has the two halogen atoms on the same carbon. An example is 2,2-dibromopropane.)
