Tb₂Ni₂Mg₃: a new structure type derived from the Ru₃Al₂B₂ type

Tb₂Ni₂Mg₃ is a new structure type, derived from Ru₃Al₂B₂, which can be viewed as the first representative of a homologous linear structure series based on the α-Fe, CsCl and AlB₂ structure types. The Tb atoms in the structure are enclosed in 17-vertex polyhedra, while rhombododeca­hedra and distorted rhombododeca­hedra surround the Mg atoms, and equatorially tricapped trigonal prisms form around the Ni atoms.
