| 摘 要： | Three complexes Cu（ppca）2（H2O）2（NO3）2 （1）, Cu2（μ-OH）2（ppca）2（H2O）4）·（ClO4）2 （2） and Cu2（μ-CH3COO）4（ppca）2（3） have been synthesized by the reaction of copper（Ⅱ） salts with N-phenyl-4-pyridinecarboxamide （ppca） and characterized. For anions, in complex 1, NO3^- coordinated with copper（Ⅱ）, in complex 2 perchlorate anion did not take part in coordination, the copper（Ⅱ） cations were connected by μ-OH to form a dinuclear unit, and complex 3 had a dimeric copper（Ⅱ） carboxylate paddle-wheel core. Noncovalent interactions linked these complexes to form supramolecular networks. Different coordinating modes of anions controlled modes of intennolecular interactions, which resulted in different final structures.

| Abstract: | Three complexes Cu(ppca)2(H2O)2(NO3)2 ( 1 ), Cu2(μ‐OH)2(ppca)2(H2O)4}·(ClO4)2 ( 2 ) and Cu2(μ‐CH3COO)4(ppca)2 ( 3 ) have been synthesized by the reaction of copper(II) salts with N‐phenyl‐4‐pyridinecarboxamide (ppca) and characterized. For anions, in complex 1 , NO3‐ coordinated with copper(II), in complex 2 perchlorate anion did not take part in coordination, the copper(II) cations were connected by μ‐OH to form a dinuclear unit, and complex 3 had a dimeric copper(II) carboxylate paddle‐wheel core. Noncovalent interactions linked these complexes to form supramolecular networks. Different coordinating modes of anions controlled modes of intermolecular interactions, which resulted in different final structures. |
