Developing novel luminescent materials for sensitive and rapid detection of heavy metal ions, organic solvents and organochlorine pesticides is vital for environmental monitoring. Herein, a new Ag(i) luminescent coordination polymer [Ag(3-dpyb)(H 3 odpa)]·H 2 O (LCP 1) (3-dpyb = N , N '-bis(3-pyridinecarboxamide)-1,4-butane, H 4 odpa = 4,4'-oxydiphthalic acid) was obtained by a hydrothermal reaction and characterized by single crystal, powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis and luminescence spectroscopy. LCP 1 is a three-dimensional (3D) supramolecular framework formed from 1D [Ag-3-dpyb-H 3 odpa] n chains and H-bond interactions. The luminescence sensing study of LCP 1 for recognizing organic solvents, organochlorine pesticides and heavy metal ions was performed, which demonstrated it to be a potential luminescent sensor for Hacac, NB, 2,6-DCN, Fe 2+ , Hg 2+ , and Fe 3+ . Fe 2+ , Hg 2+ , and Fe 3+ in river water were determined using LCP 1 with satisfying recovery.
