Antiferromagnetic crystals with F and Cl
I was just looking over a general list of antiferromagnetic crystals and couldn't help but notice that half the list were fluoride or chloride compounds which are often corrosive or otherwise problematic from a handling point of view (eg FeF2). This may seem a stupid question, but, are these two traits related?

Not that I know of.
There are plenty of intermetallic antiferromagnets (for example in the ThCr2Si2 crystal structure where you put a rare earth on the Th position) and simple oxides such as FeO, CuO, NiO. The parent compounds of the high-Tc superconductors are AFM. Books and books have been filled with listings of antiferromagnetic materials.
