A Unique Zigzag Strand of Silver Perchlorate with Bis(3-pyridyl)cyclotetramethylenesilane

Abstract

Metal-based coordination polymers with specific motifs have been attracted due to both aesthetic facet and potential applicability such as electrical conductivity, molecular magnet, host-guest chemistry, crystal bending effect, and catalysis. New motifs can be designed by selecting the coordination geometry of central metals, the structure of spacer ligands, the kinds of counterions, and reaction conditions. Among diverse elegant efforts to find key factors in the development of rational molecular structures, the use of new organic tectonics that can bridge two or more metal centers is of current interest. The appropriate angle and flexible components of the tectonics play important roles in establishing a rational design strategy. In this context, recently, silicone-containing bipyridyl tectonics have been developed and explored for a fascinating class of materials containing diverse architectures and functions. In order to explore the effects of angle constraint of the spacer ligand on the coordination polymerization, we report a unique structure and related properties of [AgL]ClO4 prepared by the reaction of AgClO4 with bis(3-pyridyl)cyclotetramethylenesilane (L). L is a new tectonic ligand that possesses a rigid cyclotetramethylene moiety, confor-
