| 摘 要： | The solvothermal reaction of 5-nitroisophthalic acid （H2nip）, 1,3-bis（4-pyridyl）pro- pane （bpp） and Co（NO3）2·6H：O at 130 and 160 ℃ gave rise to two polymorphic complexes Co（bpp）（H20）（nip）], （1, 2）. Complex I belongs to monoclinic, space group C2/c with a = 14.489（6）, b = 18.242（8）, c = 19.414（9） A, β = 123.09（3）°, V = 4299（3） A3, Z = 8, C21H19CoN3O7, Mr = 484.32, Dc= 1.497 g/cm3, F（000） = 1992,/l = 0.847 mm-1. In complexes I and 2, bpp connects Co（II） into different 1D chains which are bridged by nip to form similar two-fold interpenetrating 3D frameworks.
