It is ionic. The dichromate ion, Cr2O72-, with the structure [O3Cr-O-CrO3]2-, consists of covalently bonded oxygen and chromium atoms (the electronegativities of Cr and O are 1.6 and 3.5, respectively, so the bonds are highly polar). This oxyanion is bonded ionically to magnesium ions, Mg2+. See Cotton and Wilkinson, Advanced Inorganic Chemistry, for more on the dichromate ion. Magnesium dichromate is the only alkaline earth dichromate that is appreciably soluble in water.
Magnesium bromide is an ionic compound, not covalent.
