Abstract

Cs2Pr10Co2I17 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Cs is bonded to twelve I atoms to form distorted CsI12 cuboctahedra that share corners with fourteen PrCoI5 octahedra, edges with two equivalent CsI12 cuboctahedra, a faceface with one CsI12 cuboctahedra, and faces with six PrCoI5 octahedra. The corner-sharing octahedra tilt angles range from 36–49°. There are a spread of Cs–I bond distances ranging from 4.18–4.52 Å. There are four inequivalent Pr sites. In the first Pr site, Pr is bonded to one Co and five I atoms to form PrCoI5 octahedra that share corners with three equivalent CsI12 cuboctahedra, corners with two PrCoI5 octahedra, edges with six PrCoI5 octahedra, and a faceface with one CsI12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–10°. The Pr–Co bond length is 2.84 Å. There are a spread of Pr–I bond distances ranging from 3.18–3.46 Å. In the second Pr site, Pr is bonded to one Co and five I atoms to form distorted PrCoI5 octahedra that share corners with two equivalent CsI12 cuboctahedra, corners with five PrCo2I4 octahedra, edges with five PrCoI5 octahedra, and faces with two equivalent CsI12 cuboctahedra. The corner-sharing octahedra tilt angles range from 6–11°. Themore »« less
