CsBPb(IF2)2 crystallizes in the monoclinic C2 space group. Cs(1) is bonded in a 10-coordinate geometry to four equivalent I(1), two equivalent F(2), and four equivalent F(1) atoms. B(1) is bonded in a tetrahedral geometry to two equivalent F(1) and two equivalent F(2) atoms. Pb(1) is bonded in a 4-coordinate geometry to four equivalent I(1) atoms. I(1) is bonded to two equivalent Cs(1) and two equivalent Pb(1) atoms to form distorted corner-sharing ICs2Pb2 trigonal pyramids. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to two equivalent Cs(1) and one B(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Cs(1) and one B(1) atom.
CsBPb(IF2)2 crystallizes in the monoclinic C2 space group. Cs(1) is bonded in a 10-coordinate geometry to four equivalent I(1), two equivalent F(2), and four equivalent F(1) atoms. There are two shorter (4.04 Å) and two longer (4.09 Å) Cs(1)-I(1) bond lengths. Both Cs(1)-F(2) bond lengths are 3.61 Å. There are two shorter (3.49 Å) and two longer (3.79 Å) Cs(1)-F(1) bond lengths. B(1) is bonded in a tetrahedral geometry to two equivalent F(1) and two equivalent F(2) atoms. Both B(1)-F(1) bond lengths are 1.42 Å. Both B(1)-F(2) bond lengths are 1.42 Å. Pb(1) is bonded in a 4-coordinate geometry to four equivalent I(1) atoms. All Pb(1)-I(1) bond lengths are 3.18 Å. I(1) is bonded to two equivalent Cs(1) and two equivalent Pb(1) atoms to form distorted corner-sharing ICs2Pb2 trigonal pyramids. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to two equivalent Cs(1) and one B(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Cs(1) and one B(1) atom.
