Two new metal-chalcogenide-cluster-based frameworks with single metal ions of Zn 2+ (/Sb 3+ ) serving as inter-cluster linkers.

Two new metal-chalcogenide-cluster-based frameworks, in which P1-ZnSnS clusters are linked to each other by both corner-shared S 2- ions and single metal ions of Zn 2+ (or Sb 3+ ) to form one new 3D (3,4)-connected network (MCCF-22) and one 2D-layered framework (MCCF-23), respectively, are reported. Notably, MCCF-22 exhibits good performance toward photodegradation of methylene blue compared with its analogue framework with only S 2- ions as the linker.
