Lanthanoids borides

The carbides Ln2C3 and LnC2 are formed when the metals are heated with carbon. The LnC2 carbides adopt the same structure as CaC2 (see Section 13.7), but the C—C bonds (128 pm) are significantly lengthened (119 pm in CaC2). They are metallic conductors and are best formulated as Ln [C2] (e ). Lanthanoid borides were discussed in Section 12.10 halides are described below.
