Structure of new porous compounds after annealing in vacuum

Dehydration process in recently synthesized porous inorganic salts formed b y large cluster anions [Re6X8(CN)(6)](4-) (X=S, Se), transition metal catio ns and water molecules has been investigated. Desolvation process of the co mplex Co(DMF)(6)[Mo6Br8(NCS)(6)], where DMF - dimethylformamide, has been s tudied. CoK, MoK and ReL3 XAFS measurements of these new complicated compou nds before and after annealing in vacuum at temperature up to 250 degreesC were performed. Changes of electronic and spatial structure of these compou nds under the heating process have been established and adequate structural models of the amorphous compounds obtained are suggested and discussed.
