It is a covalent compound.

Here's why:

* Electronegativity Difference: The electronegativity difference between antimony (Sb) and bromine (Br) is not large enough to form a purely ionic bond. Antimony has an electronegativity of 2.05, while bromine has an electronegativity of 2.96. This difference (0.91) falls in the range for polar covalent bonds.

* Nature of the Elements: Antimony is a metalloid and bromine is a nonmetal. While metalloids can sometimes form ionic compounds with nonmetals, in this case, the bonding is primarily covalent.

In SbBr3, the bromine atoms share electrons with the antimony atom, forming covalent bonds. This results in a molecule with a trigonal pyramidal shape.
