Title: An Obscured or Nonexistent Binary Intermetallic, Co 7 Pr 17 , Its Existent Neighbor Co 2 Pr 5 , and Two New Ternaries in the System Co/Sn/Pr, CoSn 3 Pr 1–x , and Co 2–x Sn 7 Pr 3

Abstract

Four compounds are reported in this study. Co 7Pr 17 (10, cP96, P2 13, a = 13.4147(8) Å, Z = 4), either non-existent or obscured in the Co/Pr phase diagram has been obtained from a PrBr 3 flux. With 29.2 mol% Co, it is close to Co 2Pr 5 (28.6 mol% Co, 2, C 2Mn 5 type of structure, mC28, C2/c, a = 16.5471(7) Å, b = 6.5107(3) Å, c = 7.1067(3) Å, β = 96.230(3)', Z = 4), existent in the Co/Pr phase diagram, produced by arc-melting of a stoichiometric mixture of the metals. The addition of the reactive metal tin to Co/Pr mixtures yielded two new ternary polar intermetallics, CoSn 3Pr 1-x (x = 0.04, 11, RuSn 3La type, cP40, Pm3 -n, a = 9.587(3) Å, Z = 8) and Co 2–xSn 7Pr 3 (x = 0.78, 12, Ni 2–xSn 7–yCe 3 type, oC24, Cmmm, a = 4.5043(4) Å, b = 27.227(2) Å, c = 4.5444(3) Å, Z = 2). Electronic structure calculations reveal extensive heteroatomic Co-Pr interactions in the binaries with little homoatomic contributions. With tin as the third component in the ternaries, heteroatomic Co–Sn and Sn–Pr bonding interactions are dominant, following the sequence of coordination spheresmore » around Co.« less
