Title: Synthesis and crystal structures of Nd{sub 6}Pt{sub 13}In{sub 22}, Sm{sub 6}Pt{sub 12.30}In{sub 22.70}, and Gd{sub 6}Pt{sub 12.48}In{sub 22.52}

Abstract

The rare earth-platinum-indides Nd{sub 6}Pt{sub 13}In{sub 22}, Sm{sub 6}Pt{sub 12.30}In{sub 22.70}, and Gd{sub 6}Pt{sub 12.48}In{sub 22.52} were synthesized from the elements by arc-melting of the components. Single crystals were grown using special annealing sequences. The three indides were investigated by X-ray powder and single crystal diffraction: Tb{sub 6}Pt{sub 12}In{sub 23} type, C2/m, Z=2, a=2811.9(6), b=441.60(9), c=1486.6(3)pm, {beta}=112.10(3){sup o}, wR{sub 2}=0.0629, 3645 F{sup 2} values, 126 variables for Nd{sub 6}Pt{sub 13}In{sub 22}, a=2821.9(6), b=443.06(9), c=1481.0(3)pm, {beta}=112.39(3){sup o}, wR{sub 2}=0.0543, 3679 F{sup 2} values, 127 variables for Sm{sub 6}Pt{sub 12.30}In{sub 22.70}, and a=2818.5(6), b=439.90(9), c=1480.9(3)pm, {beta}=112.29(3){sup o}, wR{sub 2}=0.0778, 3938 F{sup 2} values, 127 variables for Gd{sub 6}Pt{sub 12.48}In{sub 22.52}. Most platinum atoms in these structures have a distorted trigonal prismatic coordination by rare earth metal and indium atoms. Together, the platinum and indium atoms build up a complex three-dimensional [Pt{sub 12+x}In{sub 23-x}] polyanionic network in which the rare earth metal atoms fill distorted pentagonal and hexagonal channels. The 2c Wyckoff site in these structures plays a peculiar role. This site is occupied by indium in the prototype Tb{sub 6}Pt{sub 12}In{sub 23}, while platinum atoms fill the 2c site in Nd{sub 6}Pt{sub 13}In{sub 22}, leading to a linear Pt{sub 3} chain withmore » Pt-Pt distances of 275pm. The crystals with samarium and gadolinium as rare earth metal component show mixed Pt/In occupancies.« less
