Abstract

The phosphide ScIrP was synthesized from the elements in a bismuth flux and characterized by powder and singlecrystal X-ray diffraction: ZrNiAl type, P6̄2m, Z = 3, a = 637.2(3), c = 389.2(2) pm, wR2 = 0.0280, 250 F2 values, 15 variables. The two crystallographically independent phosphorus sites have tricapped trigonal-prismatic metal coordination P1Ir3Sc6 and P2Ir6Sc3. The shortest interatomic distances occur for Ir-P (244 - 251 pm) within the 3D [IrP] network in which the scandium atoms fill cavities of coordination number 15 (4 Sc + 6 Ir + 5 P).
