Syntheses, Crystal Structures, and Reversible Structural Transformation of Two Zinc Coordination Polymers

Syntheses, Crystal Structures, and Reversible Structural Transformation of Two Zinc Coordination Polymers

Two zinc coordination polymers, [Zn(H2dhtp)(2,2′-bpy)(H2O)] (1) and [Zn(H2dhtp)(2,2′-bpy)] (2) (H4dhtp: 2,5-dihydroxyterephthalic acid), have been simultaneously synthesized from a one-pot reaction system. Pure phase of 1 could be obtained by varying the ratio of Zn(II) salt/H4dhtp, while that of 2...

Zusammenfassung:Two zinc coordination polymers, [Zn(H2dhtp)(2,2′-bpy)(H2O)] (1) and [Zn(H2dhtp)(2,2′-bpy)] (2) (H4dhtp: 2,5-dihydroxyterephthalic acid), have been simultaneously synthesized from a one-pot reaction system. Pure phase of 1 could be obtained by varying the ratio of Zn(II) salt/H4dhtp, while that of 2 could not. A reversible structural transformation between 1 and 2 was observed by heating and immersing in mother liquid, and their photoluminescent properties were also studied.
