SYNTHESES, STRUCTURES AND PHYSICAL PROPERTIES OF CYANIDE-BRIDGED M(II)-Ni(II) BIMETALLIC COMPLEXES WITH 2-PYRIDINEETHANOL (M(II) = Fe, Co and Ni)

Öz:

Bu çalışmada [ML2Ni(?-CN)2(CN)2] (L= 2-piridinetanol (hepH); M = Fe(II), Co(II) veya Ni(II); bundan sonra M-hepH-Ni olarak kısaltılmıştır.) formülü ile verilen siyanür kompleksleri ilk kez elde edilmiştir. Bu komplekslerin yapıları kırmızı-altı ve Raman spektroskopisi, termal ve elementel analiz teknikleri kullanılarak belirlenmiştir. Komplekslerin elektriksel özellikleri dört uç metodu, manyetik özellikleri ise Evans metodu kullanılarak araştırılmıştır. Titreşim işaretlemeleri tüm gözlenen bandlar için elde edilmiş ve spektral özelliklerin komplekslerin yapılarını destekledikleri görülmüştür. Komplekslerin termal davranışları kuru havada 30 - 700 ºC sıcaklık aralığında TG, DTG ve DTA eğrileri kullanılarak incelenmiştir. Termal analiz eğrilerine göre, hepH ligandının ve siyanür grubunun yapılardan uzaklaştıkları görülmüştür. Son bozunma ürünlerinin metal oksitler olduğu bulunmuştur. Manyetik ölçümlerde komplekslerin deneysel ve teorik manyetik moment değerleri karşılaştırılmıştır. Ayrıca, Fe-hepH-Ni, Co-hepH-Ni ve Ni-hepH-Ni komplekslerinin paramanyetik oldukları belirlenmiştir.

2-PİRİDİNETANOL İLE SİYANÜR-KÖPRÜLÜ M(II)-Ni(II) İKİ METALLİ KOMPLEKSLERİN SENTEZİ, YAPISI VE FİZİKSEL ÖZELLİKLERİ (M(II) = Fe, Co ve Ni)

Öz:

In this study, cyanide complexes with chemical formula [M(hepH)2Ni(?-CN)2(CN)2] (hepH = 2-pyridineethanol; M = Fe(II), Co(II) and Ni(II); abbreviated to hereafter M-hepH-Ni) were obtained for the first time. The structures of these complexes were determined by using FT-IR and Raman spectroscopies, thermal and elemental analyses. The electrical and magnetic properties of the complexes were investigated by four-probe and Evans methods, respectively. Vibration assignments are obtained for all the observed bands and the spectral feature has been shown supported to the structure of complexes. Thermal behaviors of these complexes were examined using TG, DTG and DTA curves in the temperature range 30-700 °C in the static air atmosphere. According to thermal analysis curves, it has seen that neutral ligands (hepH) are released and cyanide ligands are decomposed in the complexes, followed usual decomposition mechanism. The final decomposition products are found to be the corresponding metal oxides. The magnetic measurements of the complexes are compared with experimental and theoretical values of the magnetic moment. Furthermore, Fe-hepH-Ni, Co-hepH-Ni and Ni-hepH-Ni complexes are determined to be paramagnetic.
