Symmetry codes:#1:-x,y,-z+1/2;#2:-x+1,-y+1,z+1/2;#3:x-1,-y+1,-z for 1;#1:y-1/4,-x+3/4,z+1/4;#2:y-3/4,x+1/4,z+1/4;#3:-y+3/4,-x+5/4,z+1/4 for 2.

Two single crystals with dimensions of 0.22 mm×0.16 mm×0.08 mm for 1 and 0.18 mm×0.14 mm×0.10mm for 2 were mounted on glass fibers for measurement,respectively.X-ray diffraction intensity data were collected on a Bruker APEXⅡCCD diffractometer equipped with a graphite-monochromatic Mo Kαradiation(λ=0.071 073 nm)using theφ-ωscan mode at 293(2)K.Data reduction and empirical absorption correction were performed using the SAINT and SADABS program[27],respectively.The structures were solved by the direct method using SHELXS-2016[28]and refined by full-matrix least squares on F2using SHELXL-2016[29].All of the non-hydrogen atoms were refined anisotropically.The solvent molecules in 2were highly disordered and were removed from the diffraction data by the SQUEEZE routine of PLATON program.The final formula of 2 were determined by single-crystal structures,elemental analysis results and TGA.The details of the crystal parameters,data collection and refinement for 1 and 2 are summarized in Table 1,and selected bond lengths and angles with their estimated standard deviations are listed in Table 2.
