| Abstract | [CuL(ClO$_{4}$)$_{2}$] complex of 14-membered hexaazamacrocyclic ligand (L = 6,13-dimethyl-3,10-dioctyl-1,3,5,8,10,12-hexaazacyclotetradecane) was synthesized by template condensation reaction of 1,2-diaminopropane, octylamine, and formaldehyde in ethanol. The product was characterized by elemental analysis, Fourier-transformed infrared spectroscopy (FT-IR), ultraviolet–visible spectroscopy (UV–vis), diffused reflectance spectroscopy (DRS), liquid chromatography-mass spectrometry (LC–MS), and X-ray crystallographic technique. Thermal behavior of this complex was studied by thermogravimetric analysis (TGA). The IR and other spectral properties were consistent with the result from X-ray diffraction. The electronic absorption spectra of [CuL(ClO$_{4}$)$_{2}$] complex showed one band at 500 nm corresponding to $^{2}$B$_{1g}$ → $^{2}$B$_{2g}$ transition. The complex crystallized in the triclinic space group of Pī with a = 8.1307(6) Å, b = 9.3579(7) Å, c = 13.3930(10) Å, α = 95.932(2)°, β = 98.579(2)°, and γ = 114.478(2)°. The copper(II) ion of the macrocyclic cation displayed a tetragonally distorted octahedral geometry with four nitrogen atoms in the equatorial plane and two oxygen atoms from the perchlorate ions weakly coordinated to the copper(II) ion in the axial positions. The complex exhibited only weak luminescent property.A new macrocyclic complex that can be easily obtained from the one-pot synthesis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
