The material structure described by K2Pb2Si2O crystallizes in the hexagonal P6/mmm space group. K(1) is bonded to two equivalent Pb(1) and three equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing KPb2O3 trigonal bipyramids. Pb(1) is bonded in a distorted linear geometry to two equivalent K(1) atoms. Si(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a linear geometry to six equivalent K(1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
