An Unusual Three-Dimensional Coordination Network Formed by Parallel Polycatenation of Two-Fold Interpenetrated (6,3) Layers Based on a Novel Three-Connecting Ligand

The novel tridentate ligand 1,3,5-tris(4-cyano-phenoxymethyl)-2,4,6-trimethylbenzene (1) together with silver-(I) triflate has afforded the interesting coordination polymer [Ag(1)(CF3SO3)].0.5H2O, containing undulated (6,3) layers of hexagonal meshes, with alternating Ag and (1) triconnected centers, entangled into 2-fold parallely interpenetrated sheets, which, furthermore, are polycatenated to generate an unique three-dimensional array.
