Synthesis and characterization of novel grid coordination polymer networks generated from unsymmetrically bridging ligands.
Self-assembly between simple unsymmetrical ligands, such as 1-(3-pyridyl)-2-(4-pyridyl)ethene (L(1)) and 1-methyl-1'-(3-pyridyl)-2-(4-pyrimidyl)ethene (L(2)), and Co(NCS)(2) affords the unprecedented two-dimensional grid coordination polymers [Co(L(1))(2)(NCS)(2)](infinity) (1) and [Co(L(2))(2)(NCS)(2)](infinity) (2), respectively, with novel topological features which cannot be achieved using symmetrically bridging ligands.
