【Abstract】 Two 2 D inorganic organic hybrid layered network materials Zn(BDC)(C 3H 3N 2)·(DMF)(1) and Co 2 (BDC) 2(C 5H 5N) 4·2(DMF)(C 5H 5N)(2) were synthesized under mild synthesis condition. Their crystal structures were determined by using single crystal X ray diffraction. Crystal structures were solved by direct method and refined by full matrix least square method. Compound 1 is monoclinic, space group C2/c with a =2 1059(4) nm, b =1 0316(2) nm, c =1 4836(3) nm, β =99 09(3)°, V =3 1826(11) nm 3, Z =4, D X=1 543 Mg/m 3, C 14 H 14 N 3O 5Zn, M r=369 65, μ =1 571 mm -1 , F (000)=1512, R =0 0697, R w=0 2018, and compound 2 is monoclinic, space group P2(1)/n with a =1 0829(2) nm, b =1 5431(3) nm, c =1 4428(3) nm, β =101 65(3)°, V =2 3612(8) nm 3, Z =2, D X=1 391 Mg/m 3, C 47 H 47 N 7O 10 Co 2, M r=987 78, μ =0 767 mm -1 , F (000)=1024, R =0 0652, R w=0 1888. They are layered networks with 0.9 nm×0.9 nm pore.更多还原
