Abstract
As a continuation of our recent investigations on coordination polymer/metal–organic framework containing compounds, herein, four new coordination polymers, namely, {Co2(ADA)2(px2ampy)}n (1), {Cd(ADA)(px2ampy)0.5}n (2), {Co2(IPTA)2(px2ampy)}n (3), {Mn(IPTA)(px3ampy)}n (4) have been synthesized, based on the flexible dicarboxylate ligand H2ADA and rigid dicarboxylate ligand H2IPTA along with long flexible bis-pyridyl linkers as coligand (where H2ADA = 1,3-adamantanediacetic acid; H2IPTA = isopthalic acid; px2ampy = 1,4-bis(2-pyridylaminomethyl)benzene; px3ampy = 1,4-bis(3-pyridylaminomethyl)benzene). Compounds 1–4 have been characterized by routine elemental analysis, IR spectroscopy, and thermogravimetric (TG) analysis and unambiguously by single crystal X-ray diffraction analysis. The solid-state luminescent property of compound 2 has been additionally characterized. Compound 1 is a two-dimensional (2D) framework, constructed by the connectivity of Co2 paddle-wheels as secondary building units (SBUs) and...
