The crystal structure described by KK4InPb8 crystallizes in the trigonal R-3m space group. The structure consists of three 7440-09-7 atoms inside a K4InPb8 framework. In the K4InPb8 framework, there are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to nine equivalent Pb(1) atoms. In the second K site, K(3) is bonded in a 1-coordinate geometry to one Pb(2) and six equivalent Pb(1) atoms. In(1) is bonded in a distorted cuboctahedral geometry to six equivalent Pb(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 11-coordinate geometry to two equivalent K(3), three equivalent K(1), one In(1), one Pb(2), and four equivalent Pb(1) atoms. In the second Pb site, Pb(2) is bonded in a distorted single-bond geometry to one K(3) and three equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
