Abstract: This thesis describes synthesis and structural studies of Cu(II), Co(II) and Zn(II) metal coordination polymers and Au(I) metal-macrocycles, as well as focuses on the following: (i) synthesizing coordination polymers of interesting topologies, (ii) investigation of water clusters hosted by coordination polymers and (iii) aligning the olefinic C=C bonds for photochemical [2+2] cycloaddition reaction in the solid-state. In this study, (H2O)7 aggregates of different morphologies inside the Cu(II) coordination polymers have been investigated. Influence of anions and auxiliary ligands on the structural alteration of water clusters via single-crystal to single-crystal (SCSC) transformation have also been explored. Photochemically induced structural transformations of various interpenetrated 3D pillar-layered Zn(II) coordination polymers are studied. The infinite pairs of olefinic C=C bonds of trans-1,2-bis(4-pyridyl)ethylene (bpe) ligands acting as pillars undergo 100% SCSC photochemical [2+2] cycloaddition reactions. Further, 100% photodimerization obtained in case of conjugated C=C bonds in trans, trans-muconic acid (H2muco) aligned in Au(I) macrocylic rings.
