Yeni Ni(II) iyon-çifti kompleksinin sentezlenmesi ve 3D kristal yapısı

Öz

Yeni Ni(II) iyon-çifti kompleksi, [BzTPP][Ni(dto)₂] [(dto)^2- = ditiooksalat ve (BzTPP)⁺= benziltrifenilfosfonyum] sentezlendi ve tek kristal X-ışını kırınımı yöntemi ile karakterize edildi. Kristal yapı analizi kompleksin monoklinik uzay grubu P2₁/c'de kristallendiğini ve asimetrik biriminde birbirinden ayrık olarak [BzTPP]⁺ organik katyonu ve [Ni(dto)₂]^2- kompleks anyonun yarısından oluştuğunu göstermektedir. Nikel atomu dört koordinatlıdır ve kare düzlem koordinasyon geometrisine sahiptir. Kristal yapıda, organik katyonlar ve inorganik anyonlar moleküller arası C–H···O hidrojen bağlarıyla ve C–H···π ve π−π etkileşimleriyle birbirlerine bağlanırlar, buda üç boyutlu kristal yapının oluşmasını ve kafes yapının kararlılığını sağlar.

Synthesis and 3D crystal structure of new Ni(II)-ion-pair complex

Öz

The new Ni(II) ion-pair complex, [BzTPP][Ni(dto)₂] [(dto)^2- = dithiooxalate and (BzTPP)⁺= benzyltriphenylphosphonium] was synthesized and characterized by single crystal X-ray diffraction method. The crystal structure analysis indicates that complex crystallizes in the monoclinic space group P2₁/c and its asymmetric unit consists of discrete one [BzTPP]⁺ organic cation and one-half of [Ni(dto)₂]^2- complex anion. The nickel atom is four coordinate and square planar coordination geometry. In the crystal structure, the organic cations and inorganic anions are linked with the intermolecular C–H···O hydrogen bonds as well as C–H··· π and π−π interactions which form 3D crystal structures and ensure the lattice stability.
