    • Synthesis of [Er(H2O)(C5H2N2O4)(TA)0.5]n (1). A mixture of imidazole-4, 5-dicarboxlylate (0.156 g; 1 mmol), terephthalate (0.166 g; 1 mmol), Er2O3 (0.191 g; 0.5 mmol), and H2O (12 mL) was heated to 160 °C for 80 h in a 20 mL Teflon-lined stainless-steel autoclave and was then cooled to room temperature at 10 °C h-1 to obtain pink plate-like single crystals of 1 (yield: 58% based on erbium). Anal. Calcd for ErC9H6N2O7 (%): C, 25.65; H, 1.44; N, 6.65. Found: C, 25.67; H, 1.46; N, 6.68. IR (KBr, cm-1): 3442 m, 3221 m, 1667 m, 1415 s, 1186w, 1136 m, 941 s, 781 m, 733 m, 520w.

    • Single crystal X-ray diffraction data collections for 1 was performed on a Bruker Apex II CCD diffractometer operating at 50 kV and 30 mA using Mo Ka radiation (λ = 0.71073 Å) at 296 K. Data collection and reduction were performed using the SMART and SAINT software [32]. A multi-scan absorption correction was applied using the SADABS program [32]. The two structures were solved by direct methods and refined by full-matrix least squares on F2 using the SHELXTL program package [33]. Hydrogen atoms were located from difference Fourier maps and a riding model. Selected bond lengths and angles are given in Table S1. Crystallographic data for complex 1: ErC9H6N2O7, FW = 421.42, Monoclinic, Space group P21/c with a = 13.1277(6) Å, b = 6.591(3) Å, c = 12.8486(6) Å. V = 1104.75(9) Å3 Z = 4, F(000) = 792, GOF = 1.027, R1 = 0.0171, wR2 = 0.0388 [I > 2σ(I)].
