They exist! Boridecarbides of transition metals . A whole series of Nb compounds was prepared from syntheses in Cu/Al melts with Nb 3 B 3 C, Nb 4 B 3 C 2 , Nb 7 B 4 C 4 , and Nb 7 B 6 C 3 . Their crystal structures can be explained easily with a simple building‐set principle based on the binary components NbC, Nb 2 B 3 , and Nb 3 B 4 .
