The conventional view of actinides is that they’re basically heavy lanthanides, with bonding driven by ionic interactions. A new study of a californium borate complex demonstrates that that view may be wrong. Wrap a Cf(III) center in polyborate chains and it looks much like a transition metal with covalent bonds to ligands, according to a team led by Thomas E. Albrecht-Schmitt of Florida State University; Laura Gagliardi of . . .
