An Obscured or Nonexistent Binary Intermetallic, CO7Pr17, Its Existent Neighbor Co2Pr5, and Two New Ternaries in the System Co/Sn/Pr, CoSn3Pr1−x, and Co2−xSn7Pr3
Abstract
<p>Four compounds are reported in this study. Co<sub>7</sub>Pr<sub>17</sub>(10, cP96, P2<sub>1</sub>3, a = 13.4147(8) Å, Z = 4), either nonexistent or obscured in the Co/Pr phase diagram, has been obtained from a PrBr<sub>3</sub>flux. With 29.2 mol % Co, it is close to Co<sub>2</sub>Pr<sub>5</sub>(28.6 mol % Co, 2, C<sub>2</sub>Mn<sub>5</sub>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<sub>3</sub>Pr<sub>1</sub>−<sub>x</sub>(x = 0.04, 11, RuSn<sub>3</sub>La type, cP40, Pm3n, a = 9.587(3) Å, Z = 8) and Co<sub>2</sub>−<sub>x</sub>Sn<sub>7</sub>Pr<sub>3</sub>(x = 0.78, 12, Ni<sub>2</sub>−<sub>x</sub>Sn<sub>7</sub>−<sub>y</sub>Ce<sub>3</sub>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 spheres around Co.</p>
