A new dinuclear MnII compound C42H62Mn2N2O10.C2H6O is synthesised, and X-ray diffraction, IR, UV and photoluminescence measurements were performed. According to structural analysis studies, the compound has a bis(hydoxy)(carboxylato)-bridged dinuclear MnII structure. Each MnII atom has an axially elongated, distorted octahedral geometry. The compound exhibits paramagnetic properties. Photoluminescence studies of the compound reveal that it shows a shift compared to the H₂L ligand. The compound emits blue light and is a suitable candidate for blue light-emitting diodes. It could contribute to the advancement of organic light-emitting diodes (OLEDs) and the innovation of optical materials

Mavi Işık Yayan Dinükleer MnII Bileşiğinin Sentezi, Kristal Yapısı ve Lüminesans Çalışmaları

Öz

Yeni bir dinükleer MnII bileşiği C42H62Mn2N2O10·C2H6O sentezlendi ve X-ışını kırınımı, IR, UV ve fotolüminesans ölçümleri yapıldı. Yapısal analiz çalışmalarına göre, bileşiğin bis(hidroksi)(karboksilato)-köprülü dinükleer MnII yapısına sahiptir. MnII iyonları, ligandın köprü oksijen atomları ve üç asetat grubunun dört oksijen atomu ile birbirine bağlanmıştır. Her bir MnII atomu, eksenel olarak uzamış bozulmuş oktahedral bir geometriye sahiptir. Bileşik paramanyetik özellik göstermektedir. Bileşiğin fotolüminesans çalışmaları, H₂L ligandı ile karşılaştırıldığında bir kayma gösterdiğini ortaya koymaktadır. Bileşik mavi ışık yaymaktadır ve mavi ışık yayan diyotlar için uygun bir adaydır. Organik ışık yayan diyotların (OLED'ler) ilerlemesine ve optik malzemelerin yenilenmesine katkıda bulunabilir
