2N:22N'-bis[(saccharinato)silver(I)]Abstract: Crystallization of the title compound, di--pyridazine-12N:22N'-bis[(2,3-dihydro-3-oxobenzisosulfonazolato-N)silver(I)], [Ag2(C7H4NO3S)2(C4H4N2)2], from acetonitrile yields both monoclinic, (I), and triclinic, (II), polymorphs. In both forms, the silver(I) ions have a slightly distorted trigonal AgN3 coordination geometry and are doubly bridged by two neutral pyridazine (pydz) ligands, generating a centrosymmetric dimeric structure. The saccharinate (sac) ligands are N-coordinated. The dihedral angles between the sac and pydz rings are 8.43 (7) and 7.94 (8)° in (I) and (II), respectively, suggesting that the dimeric molecule is nearly flat. The bond geometry is similar in both polymorphs. In (I), the dimers interact with each other via aromatic ![[pi]](/logos/entities/pi_rmgif.gif)
sac-pydz stacking interactions, forming two-dimensional layers, which are further crosslinked by weak C-H
O interactions. Compound (II) exhibits similar C-HO and - interactions, but additional C-H and Ag interactions help to stabilize the packing of the dimers.
