摘要: Abstract Two new copper(II) and cobalt(II) coordination polymers, {[Cu(Pht)(Im) 2 ] · 1.5H O} n ( 1 ) [Co(Pht)(Im) ] (where Pht 2− = dianion of o -phthalic acid; Im = imidazole) have been synthesized their crystal structures determined by X-ray crystallography. The comprise, respectively, [Cu(Im) [Co(Im) units linked bridging 1,6-phthalate ions to form infinite chains. Although there are two independent Cu atoms in the structure , each center adopts an approximately square planar mode with O from different phthalate N Im. In complex tetrahedrally coordinated. Extended hydrogen bonding networks stabilize three-dimensional both complexes. Preliminary results show that exhibit catalytic activity on oxidation cyclohexene using peroxide as oxidant under aerobic conditions at ambient temperature.
