| 摘 要： | Serf-assembly of a ferrocenyl-bridged bipyridine ligand bpef bpef=1, 1＇-bis（trans-2-pyrid-4＇-ylethenyl）ferrocene] with silver triflate in CH2Cl2/MeOH or mercuric diiodide in MeCN/CH2Cl2 gave the corresponding macrocyclic coordination complexes bpef]2AgSO3CF3]2 （1） and bpef]2Hg3I6] （2） in 93% and 89% yields, respectively, whereas the pentaerythritolyl-bridged tetrapyridine ligand ptpc ptpc=pentaerythritol tetrakis-（4-pyridinecarboxylate）] reacted with cobalt thiocyanate via self-assembly to afford the macrocyclic coordination polymer Co（NCS）2（ptpc）], （3） in 90% yield. The X-ray diffraction analyses for 1-3 confirmed their novel macrocyclic structures and revealed that （i） the two silver atoms in complex 1 have an essentially linear geometry with N-Ag-N bond angle of 175.7° and 172.9°, （ii） the geometry of the middle mercury atom in complex 2 is square-planar, while the other two mercury atoms in the other two complexes are tetrahedral, and （iii） all the cobalt atoms in complex 3 adopt an octahedral geometry. In addition, the synthetic procedure for the known tetrapyridine ligand ptpc has been improved.

| Abstract: | Self‐assembly of a ferrocenyl‐bridged bipyridine ligand bpef bpef=1,1′‐bis(trans‐2‐pyrid‐4′‐ylethenyl)ferrocene] with silver triflate in CH2Cl2/MeOH or mercuric diiodide in MeCN/CH2Cl2 gave the corresponding macrocyclic coordination complexes bpef]2AgSO3CF3]2 ( 1 ) and bpef]2Hg3I6] ( 2 ) in 93% and 89% yields, respectively, whereas the pentaerythritolyl‐bridged tetrapyridine ligand ptpc ptpc=pentaerythritol tetrakis‐(4‐pyridinecarboxylate)] reacted with cobalt thiocyanate via self‐assembly to afford the macrocyclic coordination polymer Co(NCS)2(ptpc)]n ( 3 ) in 90% yield. The X‐ray diffraction analyses for 1‐3 confirmed their novel macrocyclic structures and revealed that (i) the two silver atoms in complex 1 have an essentially linear geometry with N‐Ag‐N bond angle of 175.7°and 172.9° , (ii) the geometry of the middle mercury atom in complex 2 is square‐planar, while the other two mercury atoms in the other two complexes are tetrahedral, and (iii) all the cobalt atoms in complex 3 adopt an octahedral geometry. In addition, the synthetic procedure for the known tetrapyridine ligand ptpc has been improved. |
