Synthesis and 3D Crystal Structure of New Ni(II)-ion-pair complex

Hülya Kara


The new Ni(II)-ion-pair complex, [BzTPP][Ni(dto)2] [(dto)2- = dithiooxalate and (BzTPP)+= benzyltriphenylphosphonium] was synthesized and characterized using single crystal X-ray diffraction technique. The crystal structure analysis indicates that complex crystallizes in the monoclinic space group P21/c and its asymmetric unit contains discrete one [BzTPP]+ organic cation and 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 connected with the intermolecular C–H···O type hydrogen bonds, C–H··· π and π−π interactions which form 3D crystal structures and ensure the lattice stability.
