Synthesis and crystal structure of a new cobalt complex based on 5-bromoisophthalate and 4,4-dipyridyldisulfide ligands

摘要

A new complex, {[Co(5-Br-ip)(dps)](dpts)_(0.5)}2_n (1) (5-Br-H_2ip = 5-bromoisophthalate), has been hydrothermally synthesized by in situ generation of 4,4′-dipyridylsulfide (dps) and 4,4′-dipyridyltrisulfide (dpts) ligands from a 4,4′-dipyridyldisulfide (dpds) precursor and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray analysis. Complex 1 belongs to the monoclinic system, C2/c space group, a = 15.284(3) ?, b = 13.011(3) ?, c = 23.350(5) ?, β = 103.853(3)°, F (000) = 2464, R _1 = 0.0874, and wR_2 = 0.1912. Topology analysis reveals that complex 1 shows a (3,5)-connected 3D network with the Schl?fli symbol of (4~2.6~5.8~3)(4~2.6). Moreover, the thermal stability of 1 is also discussed.
