Molybdenum, niobium or tantalum crucibles are required to avoid alloy formation with the dysprosium.

[4] Dysprosium dichloride is capable of reducing titanium dichloride to titanium metal in a potassium chloride, sodium chloride flux.

[5] A ternary dysprosium(II) chloride compound is known with lithium: LiDy2Cl5.

This is produced by heating lithium metal and dysprosium trichloride together at 700 °C.

The crystal system of LiDy2Cl5 is monoclinic with space group C2/c 4 formulae per unit cell which has dimensions; a = 16.45.6(; b = 6.692; and c = 7.267; with β = 95.79°.
