One—dimensional Chain Topology in [Ag（C6H6NCl）2]（ClO4）,Generated through Weak Interaction between Molecules

1 INTRODUCTION It is known that the research of supramolecular chemistry and crystal engineering of coordination compound receives great interest nowadays.1~6] Supramolecules are not just collection of molecules, generally, the formation of a supramolecule is through hydrogen bonding, π-π stacking interaction and the weak interaction between molecules.1] Recently, more and more supramolecular compounds containing polymeric Ag(I) species have been described due to the coordination mode…

One-dimensional Chain Topology in [Ag(C_6H_6NCl)_2](ClO_4), Generated through Weak Interaction between Molecules

The mononuclear complex Ag(C6H6NC1)2](C1O4) has been prepared and structurally analyzed by single-crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group C2/c with unit cell parameters: a=15.5314(2), b=8.0247(8),c=15.3701 (2)A. β =118.832(2)°, V=1678.2(3)A3, Z=4, Mr=462.46, Dc=1.830Mg/m3, F(000)=912,μt (MoKa) = 1.694cm-1. The final R and wR are 0.0472 and 0.1272 for 1484 observed reflections with I≥3σ (Ⅰ). The Ag atom is coordinated by two nitrogen atoms of 4-chloromethyl-pyridine in a linear coordination geometry. Each molecule is further linked by the weak interaction between the C1 and Ag atoms to form a one-dimensional chain structure with Ag-C1 distance of 3.240(A).
