Abstract: | Polysulfonyl Amines. LXI. Silver(I) in a Novel N-Donor Environment: Synthesis and Structure of catena-Poly[(dimesylamido-N)(acetonitrile)(μ-pyrazine)silver(I)] The complex [Ag{N(SO2Me)2}(μ-pz)(MeCN)]∞ is precipitated upon adding pyrazine to an acetonitrile solution of AgN(SO2Me)2. Crystallographic data (at ?100°C); monoclinic, space group P21/c, a = 912.3(2), b = 1 396.5(3), c = 1 151.7(3) pm, β = 97.20(2)°, U = 1.4557 nm3, Z = 4. The structure consists of infinite zigzag chains in the z-direction. The chain backbone is composed of silver atoms linked by pyrazine ligands (N? Ag? N 99.4°, Ag? N 232.4 und 234.0 pm). The severely distorted tetrahedral environment of Ag is completed by an N-bonded dimesylamide anion (Ag? N 224.3 pm) and an acetonitrile molecule (Ag? N 240.9 pm). The N? Ag? N angles vary from 97.5 bis 125.7°. |
