✦ Synopsis

A new ion-pair complex, (C 14

anion, which is located on an inversion center, exhibits a planar structure. The crystal packing is governed by short C-HÁ Á ÁN and C-HÁ Á ÁS contacts between anions and cations and bystacking interactions between the phenyl groups of the cations (the centroid-centroid distance is 3.802 A ˚; symmetry code: Àx + 2, Ày + 2, Àz).

, was obtained by the direct reaction of NiCl 2 Á6H 2 O, K 2 imnt and (Bz2NH 2 py) + ÁBr À in water. The Ni II ion lies on an inversion centre and the asymmetric unit contains a (Bz2NH 2 py) + cation and one-half of the Ni(imnt) 2 2À anion. The Ni II ion adopts a square-planar coordination geometry.
