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.
