Poly[μ-bromido-μ-(2,2-dimethyl-propane-1,3-diyl diisocyanide)-silver(I)]: a powder diffraction study.

In the title compound, [AgBr(C(7)H(10)N(2))](n), adjacent Ag(I) atoms are bridged by bidentate CNCH(2)C(CH(3))(2)CH(2)NC ligands via the NC groups, forming [Ag{CNCH(2)C(CH(3))(2)CH(2)NC}](n) chains with the metal atom in a distorted tetrahedral coordination. The bromide counter-anions cross-link the Ag(I) atoms of the chains, forming a two-dimensional polymeric network {[Ag(I)(CNCH(2)C(CH(3))(2)CH(2)NC)]Br}(n) extend-ing parallel to (010). The polymeric structure is similar to that of the very recently reported Cl(-), I(-) and NO(3) (-) analogues. This gives a strong indication that 2,2-dimethyl-propane-1,3-diyl diisocyanide is a potential ligand for giving polymeric structures on treatment with AgX (X = Cl(-), Br(-), I(-) or NO(3) (-)) regardless of the counter-anion used.
