Özet

Two new complexes, [M(4-CNB)(2)(DENA)(2)(H2O)(2)] (where M: Co and Mn, 4-CNB = 4-cyanobenzoate and DENA = N,N'-diethylnicotinamide), were synthesized and characterized using different techniques (elemental analysis, FT-IR Spectroscopy, single-crystal X-ray diffraction, and TGA/DTA analysis). Looking at the crystal structure of the complexes, the metal atoms are coordinated by two nitrogen atoms from two DENA ligands, two carboxyl oxygen atoms from two 4-cyanobenzoate anions, and two oxygen atoms from two water molecules, and the complexes have distorted octahedral geometry around the metal atom center. Both complexes were crystallized with the P-1 space group in the triclinic system. The linear absorption and emission features of the complexes were recorded by UV-Vis and fluorescence spectrophotometers, respectively. Linear absorption and emission results of the complexes showed that [Mn(4-CNB)(2)(DENA)(2)(H2O)(2)] complex can be used as optical filter below 400 nm wavelength when [Co(4-CNB)(2)(DENA)(2)(H2O)(2)] complex has a good application potential among the fluorescent materials, because of its high emission intensity. In addition, the Hirshfeld surfaces analyses of complexes have been investigated in detail.
