The asymmetric unit of the title salt, {(C(12)H(20)N(4))[Ag(2)Br(4)]}(n), contains one-half of a substituted imidazolium cation, one Ag(+) and two Br(-) ions. The cation is completed by crystallographic inversion symmetry. The crystal structure is made up from polymeric sheets of {[AgBr(2)](-)}(n) anions extending parallel to (100). The basic building unit of the anion is a slightly distorted AgBr(4) tetra-hedron. A four- and 12-membered ring system is formed by corner sharing of the AgBr(4) tet ...[more]
