“Two New Arsenides, Eu7Cu44As23 and Sr7Cu44As23, With a New Filled Variety of the BaHg11 Structure”. Charkin DO, Demchyna R, Prots Y, Borrmann H, Burkhardt U, Schwarz U, Schnelle W, Plokhikh IV, Kazakov SM, Abakumov AM, Batuk D, Verchenko VY, Tsirlin AA, Curfs C, Grin Y, Shevelkov AV;, Inorganic chemistry 53, 11173 (2014). http://doi.org/10.1021/ic5017615
Abstract: Two new ternary arsenides, namely, Eu7Cu44As23 and Sr7Cu44As23, were synthesized from elements at 800 degrees C. Their crystal structure represents a new filled version of the BaHg11 motif with cubic voids alternately occupied by Eu(Sr) and As atoms, resulting in a 2 x 2 x 2 superstructure of the aristotype: space group Fm (3) over barm, a = 16.6707(2) angstrom and 16.7467(2) angstrom, respectively. The Eu derivative exhibits ferromagnetic ordering below 17.5 K. In agreement with band structure calculations both compounds are metals, exhibiting relatively low thermopower, but high electrical and low thermal conductivity.
