Two-dimensional silver(I) compound with square mesh structure, [Ag(dcpz)](ClO4) (dcpz = pyrazine-2,3-dicarbonitrile)

Silver(I) complex of pyrazine-2,3-dicarbonitrile (dcpz)] [Ag(dcpz)](ClO4) h ave been prepared and the molecular structure determined by X-ray crystallo graphy. The silver ion prefers an octahedral coordination geometry comprisi ng four nitrogen atoms from four different dcpz molecules and two oxygen at oms from ClO4- anion molecule. Each dcpz in turn bridges four Ag(I) centres leading to a square mesh arrangement of alternating metal cations and orga nic ligands. The square mesh sheet accumulates along the c-axis direction, consisting of a channel structure. (C) 1998 Elsevier Science Ltd. All right s reserved.
