A noncentrosymmetric coordination polymer based on the benzophenone-3,3′-disulfonyl-4,4′-dicarboxylate ligand exhibiting second-harmonic-generation responses

A 3D coordination polymer [CdK6(μ2-H2O)2(BODSDC)2(H2O)]n (1) based on the benzophenone-3,3′-disulfonyl-4,4′-dicarboxylate (BODSDC4−) was presented. Compound 1 crystallizes has a large second-harmonic-generation response of 1.3 times that of KDP and is type-I phase-matchable.832
