Anionic Cluster

The structure of a salt of diprotonatedendo-3-aminotropane crystallized with a copper(II) anionic cluster is reported,viz.(C8H18N2)[CuCl3(NO3)(H2O)]. Neither ion in the salt has been structurally characterized previously. In the crystal, the ions pack together to form a three-dimensional structure held together by a network of intermolecular N—H...O, O—H...Cl and N—H...Cl hydrogen-bonding interactions. Selective crystallization of the title compound can be considered as a simple method for the separation of theexoandendoisomers of 3-aminotropane.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

In the title compound, [Co(C10H8N2)3](C9H5N4O)2, the tris(2,2′-bipyridine)cobalt(II) dication lies across a twofold rotation axes in the space group C2/c. The N atoms of the three bipyridine ligands form a distorted octahedron around the cobalt ion. All the N atoms of the polynitrile 1,1,3,3-tetracyano-2-ethoxypropenide anions participate in C—H...N hydrogen bonds ensuring crystal cohesion and forming a three-dimensional structure. The structure is further stabilized by C—H...π(cation) and anion...π(cation) interactions.
