摘      要：A new 3D complex,[Co（L）（bpe）0.5（H2O）2]n（1,H2 L = 5-iodo-benzene-1,3-dioxyacetic acid,bpe = 1,2-bis（4-pyridyl）ethylene）,has been hydrothermally synthesized and structurally characterized by elemental analysis,IR and X-ray *** is formulated as C16H16 Co INO8,crystallizes in monoclinic,space group P21/c,with a = 9.806（2）,b = 6.5492（13）,c = 28.187（8） A,β = 100.12（3）°,V = 1782.0（7） A^3,Z = 4,Dc = 1.998 g/m^3,F（000） = 1052,Μr = 536.13,the final R = 0.0393 and w R = 0.0858 for 3134 observed reflections with I 〉 2σ（I）.Complex 1 displays a 3D framework with multiform helical features,left-and right-handed triple helical braids and single helical chains,which can be simplified as a new type of（3,4）-connected lattice with a（6·10^2）（6^2·10^4） SchlAfli ***,the thermal analysis of complex 1 has also been investigated.
