Reaction-dependent catenane supramolecular isomerism in cadmium coordination polymers
Two concomitant reaction-dependent supramolecular isomers of cadmium (II) coordination polymer by using Cd(NO3)2.4H2O and 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene (L), which differ in degree of interpenetration, were isolated. The structural features of these coordination polymers, {[CdL1.5(NO3)2](L0.5)}n (1) and [CdL1.5(NO3)2]n (2), were elucidated through single-crystal X-ray diffraction and further confirmed by infrared spectra (FT-IR) and powder X-ray diffraction (PXRD). X-ray structural analysis shows that compounds 1 and 2 can be simplified as a honeycomb (6,3) net. The study reveals that compound 1 forms a 2-fold interpenetrated 2D + 2D → 3D inclined polycatenated structure, in contrast to compound 2, which crystallizes as a non-interpenetrated (interdigitated) 2D motif.
