Abstract
The development of new coordination polymers (CP) and polynuclear metal complexes has received a lot of attention during the last two decades. Bridging ligands must be included in the reaction mixtures for the design of these compounds. Small pseudohalides (azide, N3- ; thiocyanate, NCS- ; cyanate, OCN-) [1-6], the larger pseudohalide namely dicynamide ion, NCNCN- (dca) [7] and aromatic heterocyclic polycarboxylates [8,9] are the most prevalent bridging ligands employed for this purpose. These ligands have the ability to bind multiple metal ions at the same time and thus act as bridging linkers to assemble metal ions in different nuclearity and in 1-, 2-, or 3-dimensional extended polymeric networks resulted in the isolation of a variety of coordination compounds with interesting molecular and crystalline architectures. [1-10] The inherent features of these compounds’
structural topologies resulted in certain interesting properties making them important in materials science applications such as gas storage [11], gas adsorption [12], nonlinear optical (NLO) activity [13] magnetism [14],molecular recognition in biological systems and medicine [15], electrical conductivity [16]and catalytic reactions [17].
