Sn2OF2 crystallizes in the tetragonal P4_2/nmc space group. Sn(1) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing SnO2F4 pentagonal pyramids. O(1) is bonded to four equivalent Sn(1) atoms to form OSn4 tetrahedra that share corners with eight equivalent F(1)Sn4 trigonal pyramids, edges with two equivalent O(1)Sn4 tetrahedra, and edges with four equivalent F(1)Sn4 trigonal pyramids. F(1) is bonded to four equivalent Sn(1) atoms to form distorted FSn4 trigonal pyramids that share corners with four equivalent O(1)Sn4 tetrahedra, corners with eight equivalent F(1)Sn4 trigonal pyramids, edges with two equivalent O(1)Sn4 tetrahedra, and edges with two equivalent F(1)Sn4 trigonal pyramids.
Sn2OF2 crystallizes in the tetragonal P4_2/nmc space group. Sn(1) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing SnO2F4 pentagonal pyramids. There is one shorter (2.16 Å) and one longer (2.45 Å) Sn(1)-O(1) bond length. There are two shorter (2.46 Å) and two longer (2.62 Å) Sn(1)-F(1) bond lengths. O(1) is bonded to four equivalent Sn(1) atoms to form OSn4 tetrahedra that share corners with eight equivalent F(1)Sn4 trigonal pyramids, edges with two equivalent O(1)Sn4 tetrahedra, and edges with four equivalent F(1)Sn4 trigonal pyramids.
