Syntheses and crystal structures of novel silver(I) coordination polymers based on linear or tetrahedral coordination environments
摘要:
Two coordination polymers containing Ag(I) atoms, (1Ag(3-pia)](PF6)}(n) (1) and {[Ag(3-pia)(2)](PF6)}(n) (2) (3-pia = N-pyridin-3-yl-isonicotinamide), have been synthesized using different solvents, and characterized by single X-ray analyses. In compound 1, Ag(l) atoms are linearly coordinated by two 3-pia ligands, resulting in one-dimensional chains. On the other hand, in compound 2, Ag(I) atoms are tetrahedrally coordinated by four 3-pia ligands, resulting in two-dimensional sheets. (c) 2008 Elsevier B.V. All rights reserved.
