Nd11Pd4In9 compound – A new member of the homological series based on AlB2 and CsCl types

The Nd11Pd4In9 compound was prepared by arc melting of pure metals under an argon atmosphere. Crystal structure was refined from X-ray single crystal diffractometer data (space group Cmmm, a = 14.843(3), b = 22.284(3), c = 3.7857(6) Å, Z = 2, RI = 0.0584, 653 F2 values). It has own structure type and together with Mn2AlB2, Cr3AlB4, Mo2FeB2 and Lu5Ni2In4 structure types belongs to homological series based on AlB2 and CsCl structure types with common formula Rm+nM2nXm.
