Why is UB2 listed under uranium(II) compounds? Shouldn't it be one of:

  • uranium(-VI), corresponding to [B+3]2U-6 (but electronegativity!);
  • uranium(X), corresponding to U+10[B-5]2 (can relativity really justify donating >6 valence electrons?);
  • uranium(VIII), corresponding to U+8(B-4–B-4) (same);
  • uranium(VI), corresponding to U+6(B-3=B-3) (plausible, albeit high oxidation for a boron alloy); or
  • uranium(IV), corresponding to U+4(B-2≡B-2) (my money's on this one)?

Uranium(II) only makes sense if the boron atoms are connected in a quadruple bond, and there is no evidence of first-row atoms making more than three bonds.
