摘要：

Reaction of NiCl2. 6H(2)O, Na-2[i-mnt] and benzo-15-crown-5 in CH3OH/CH2Cl2 at room temperature leads to [{Na(benzo-15-crown-5)}(2)Ni(mnt)(2)](n) . nCH(2)Cl(2) (1). The same reaction with Na-2[mnt] instead of Na-2[i-mnt] affords [{Na(benzo-15-crown-5)}(2)Ni(mnt)(2)](n) (2). Both complexes were isolated as crystalline products. X-ray diffraction analyses reveal that the main segments of 1 and 2 are infinite "train" structures, in which the building blocks Ni(i-mnt), or Ni(mnt), in end-to-end arrangements act as "body frames" and crown cycles standing by the body frames play the role of "cartwheel". They are joined with each other through sodium ions. (C) 1998 Elsevier Science Ltd. All rights reserved.
