Abstract:
The coordination complex of 2-amino-benzaxole (2AB) with silver(I), namely, bis(2-aminobenzoxazole-κN)silver(I) nitrate-bis(2-aminobenzoxazole (1/2), [Ag(C7H6N2O)2]NO3·2C7H6N2O or [Ag(2AB)2]NO3·(2AB)2, was synthesized from ethanol solutions of AgNO3 and 2AB. The asymmetric unit contains one mol-ecule of [Ag(2AB)2]NO3·(2AB)2, The central silver(I) atom is coordinated by two nitro-gen donor atoms from 2-amino-benzaxazole ligands in an N2 coordination set while another two 2-amino-benzaxazole ligands and one nitrate anion remain uncoordinated. The crystal structure features several intra-molecular N-H⋯O and N-H⋯N hydrogen-bonding inter-actions as well as C-H⋯π, Ag⋯π and π-π inter-actions between adjacent AB ligands. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to investigate the inter-molecular inter-actions.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
