[BW12O40]3- ve 2,2'-Bipiridil İçeren Yeni Bir Nikel(II) Kompleksinin Sentezi ve Karakterizasyonu

Keggin tipi bir polioksometalat olan {Ni(2,2'-bipy)2(H2O)[BW12O40]}3- (NiBWO) bileşiği yüksek ısıya dayanıklı cam şişede hidrotermal olarak ilk kez sentezlenmiştir. Bileşiğin yapısı elementel analiz, X-ışını kırınımı, Fourier Dönüşümlü Kızılötesi Spektroskopisi, Termogravimetrik Analiz, Taramalı Elektron Mikroskobu ve X-ışını tek kristal kırınım analizleri ile karakterize edilmiştir. X-ışını tek kristal analiz sonucu, NiBWO bileşiğinin asimetrik biriminin bir [BW12O40]5- anyonu, bir [Ni(2,2'-bipy)2(H2O)]2+ ve bir buçuk [Ni(2,2'-bipy)3]2+ katyonlarından oluştuğunu göstermiştir.

Synthesis and Characterization of a New Nickel(II) Compound Derived from [BW12O40]3- and 2,2'-Bipyridyl

A Keggin-type polyoxometalate {Ni(2,2'-bipy)2(H2O)[BW12O40]}3- (NiBWO) has been hydrothermallysynthesized in the high temperature resistant glass bottle for the first time. The structure has beencharacterized.by elemental analyses, X-ray diffraction, Fourier Transform Infrared Spectroscopy,Thermogravimetric Analysis, Scanning Electron Microscope and X-ray single crystal diffraction analyses.The X-ray single crystal study shows that the asymmetric unit of NiBWO is composed of one [BW12O40]5-anion, one [Ni(2,2'-bipy)2(H2O)]2+ and one and a half of [Ni(2,2'-bipy)3]2+ cations.
