Two compounds have been characterized structurally using single-crystal diffraction, elemental analysis, and FT-IR spectrum. In compound 1, the hexa-coordinated Cd(II) ions are bridged by BTC to form two-dimensional rhombohedral grid sheets. In compound 2, the coordination polyhedrons [CuO4N2] and [CuO3N2] are bridged by BTC to lead to a 2D framework with rectangular-shaped cavities. Two compounds of third-order nonlinear optical (NLO) properties were determined by Z-scan technique in DMSO solution. The results showed that two compounds exhibited strong NLO absorption and strong self-focusing effects. The third-order NLO absorptive coefficients β(MKS) are 5.45×10−11mW−1 for 1 and 9.81×10−11mW−1 for 2. The refractive indexes γ(MKS) are 3.96×10−18m2W−1 for 1 and 7.60×10−18m2W−1 for 2. The third-order NLO susceptibility χ(3) are calculated to be 1.25×10−11 for 1, 2.32×10−11 esu for 2, respectively. These values are larger than those of metal coordination polymers reported. Graphical Abstract: Two novel two-dimensional transition metal coordination polymers have been reported. Two compounds exhibit strong NLO absorption and strong self-focusing effects.
