Metal–organic
frameworks (MOFs) and coordination polymers
composed of thiolates as coordinating functional groups are interesting
materials with unique optical and electronical properties. Herein,
we report the preparation of KGF-4 and KGF-10, two Sn-MOF crystal
structures with bonds between Sn and thiolate. KGF-10 was isolated
as a pure phase and found to exhibit redox properties and a semiconducting
band structure, as confirmed by first-principles (density functional
theory) calculations.
