From: Noble gas separation by a MOF with one-dimensional channels
Schematic representations of (a) channels with intersecting cage and (b) one-dimensional (1D) channels with uniform size. c structure of SIFSIX-3-Zn with specified Site-1 and Site-2 in this work. COP represents the center of the pore, while COW represents the atomic center of the wall atoms. Yellow octahedron: Zn; green ball: Cl; blue ball: N; gray ball: C; and white ball: H
