摘要: Abstract A three-dimensional (3D) Yb(III)–Ag(I) heterometallic coordination polymer (HCP), formulated as [Yb2Ag2(sba)2(ina)4(H2O)3]n·nH2O (1) (Hina = isonicotinic acid, H2sba = 2-sulfobenzoic acid), has been synthesized under hydrothermal condition. It was characterized by single crystal X-ray diffraction, powder diffraction (XRD), infrared (IR) spectroscopy, elemental analysis (EA), and thermogravimetric (TGA). Solid-state photoluminescent (PL) property investigation performed on 1 revealed that it showed dual emissions in the visible near-infrared (NIR) regions upon excitation at 380 nm.
