Synthesis, crystal structure of a zigzag cluster coordination polymer {(n-Bu4N)2[Mo2O2S6Cu6Br4(4,4′-bipy)3]•0.5H2O}n

Cluster coordination polymer {(n-Bu4N)(2)[Mo2O2S6Cu6Br4(4,4 '-bipy)(3)]center dot 0.5H(2)O}(n) (4,4'-bipy=4,4'-bipyridine), has been synthesized and characterized by X-ray crystallography. The polymeric anion {[Mo2O2S6Cu6Br4(4,4'-bipy)(3)](2-)}(n) Br atoms and 4,4'-bipy ligands. Two secondary building is composed of secondary building units (SBUs) [MoOS3Cu3], units [MoOS3Cu3] and a double parallel 4,4'-bipy ligands form an octanuclear rectangular metallamacrocycle with the dimension of 1.13x0.39 nm(2), which is further connected by single bridging 4,4'-bipy ligands to form a 1D zigzag Structure.
