| Abstract: | We have synthesized two new potassium metal
coordination polymers {[K(CH3COCH3)3][Cu(btdt)2]}n
(1) and {[K(CH3CN)2][Cu(btdt)2]}n
(2) of diverse dimensionality based on a copper coordination complex [CuIII(btdt)2]1−
({btdt}2– = 2,1,3-benzenethiadiazole-5,6-dithiolate). Recrystallization
of the dark brown solid, obtained from the reaction mixture of H2btdt,
KOH and CuCl2·2H2O in MeOH, from the coordinating solvents
acetone and acetonitrile results in the formation of 3-D and 2-D extended
networks in compounds (1) and (2) respectively. The crystal structures
of (1) and (2) have been discussed in comparison with those of recently
reported sodium coordination polymers {[Na(CH3OH)4][Au(btdt)2]}n
(3), [Na(DMF)2][Au(btdt)2]}n
(4) and {[Na(CH3CN)2][Au(btdt)2]}n
(5). Compounds (1) and (2) have additionally been characterized
by routine spectroscopy including elemental analyses. |
