摘要

The reaction of N1 ,N2-bis(pyridin-4-ylmethylene)ethane-1,2-diamine (L) with Fe(NCS)₂ under various temperatures gave rise to three iron(II) coordination polymers, namely, one-dimensional [Fe(L')(NCS)₂](1), two-dimensional [Fe(L)₂(NCS)₂] H₂O (2), and one-dimensional [Fe(L)₂(NCS)₂] 2CH₂Cl ₂ 4MeOH (3). The formation of 1 involved an in situ C=C coupling reaction, L to L' [L' = 5,6-di(pyridin-4-yl)-1,2,3,4-tetrahydropyrazine], which was catalyzed by cyanide ions decomposed from thiocyanates; the manganese(II)(1a) and zinc(II)(1b) analogues of 1 were also synthesized for comparison. Magnetic studies showed that complex 1 underwent a pressure-dependent one-step incomplete spin transition whereas complexes 2 and 3 were paramagnetic in the whole temperature range.
