4-Piridin Boronik Asit Dikatyonu ve [Pd(S2C2O2)2] Dianyonu İçeren Yeni Bileşiğin Sentezi ve Kristal Yapısı

Bu çalışmada, yeni bileşik [HNC5H4B(OH)(OCH3)-4]2[Pd(S2C2O2)2] sentezlendi ve kristal yapısı tek kristal X-ışını kırınım yöntemiyle belirlendi. Bileşik, monoklinik kristal sisteminde P21/n uzay grubunda a=9.1907 Å, b=11.481 Å, c=11.107 Å, α= 90°, β =97.97°, γ =90° ve Z=2 birim hücre parametrelerinde kristallendi. Bileşiğin kristal yapısında bir {[HNC5H4B(OH)(OCH3)-4]2}2+ katyonu ve bir [Pd(S2C2O2)2]2- anyon molekülü bulunmaktadır. İnversiyon merkezinde bulunan PdII iyonu dört koordinasyonludur ve hafifçe bozulmuş kare düzlem geometriye sahiptir. Kristal yapıda, NH⋯O ve OH⋯O ve CH⋯O hidrojen bağları anyon ve katyon moleküllerini bir arada tutmaktadır. Anyon ve katyon moleküllerinin 010 yönünde ikili vida ekseni ve 010 yönüne dik kayma düzlemi simetrisi ile dizilmesi üç boyutlu bir ağ oluşmaktadır. Bu hidrojen bağlı ağ, bc düzleminde a ekseni boyunca istiflenir.

Bileşiğin kristal yapısında bir {[HNC5H4B(OH)(OCH3)-4]2}2+ dikatyonu ve bir [Pd(S2C2O2)2]2- dianyon molekülü bulunmaktadır. İnversiyon merkezinde bulunan PdII iyonu dört koordinasyonludur ve hafifçe bozulmuş kare düzlem geometriye sahiptir. Kristal yapıda, NH⋯O ve OH⋯O ve CH⋯O hidrojen bağları dianyon ve dikatyon moleküllerini bir arada tutmaktadır. Dianyon ve dikatyon moleküllerinin 010 yönünde ikili vida ekseni ve 010 yönüne dik kayma düzlemi simetrisi ile dizilmesi üç boyutlu bir ağ oluşmaktadır.
