Rodewald, Mar'yana Lukachuk, Birgit Heying, Rainer Pöttgen] Summary.: Single crystals of the indide Er2.30(1)Ni1.84(1)In0.70(1) were isolated from an arc-melted sample of the initial composition 5Er:2Ni:1In. Er2.30Ni1.84In0.70 crystallizes with a new superstructure of the Mo2FeB2 type: P4/m, a = 738.6(2), c = 361.4(1) pm, wR2 = 0.0393, 487 F2 values, 22 variables, BASF = 0.500(3) (meroedric twin matrix 010 100 00 $\bar(1)$ ). The structure may be described as an intergrowth variant of slightly distorted AlB2 and CsCl related slabs. Formation of the superstructure results in two crystallographically independent sites 1a and 1c that center the CsCl slab. These sites have different size and they are occupied by 90% In + 10% Er (1c) and 51% In + 49% Er (1a), respectively. The crystal chemical consequences are discussed on the basis of a group-subgroup scheme. Springer-Verlag/Wien, 2005 Keywords.
