“…As observed in the polymeric structures of the Cl À and NO 3 À analogues, the CNCH 2 C(CH 3 ) 2 CH 2 NC ligand in complex (I) acts in a bis-monodentate manner, and chelating behaviour is completely absent. This is undoubtedly expected for steric reasons, as the distance between the two isocyanide groups in the CNCH 2 C(CH 3 ) 2 CH 2 NC molecule is too short to allow chelate complexing (Chemin et al, 1996) (Fig. 2).…”

In order to explore the chemistry of the bidentate ligand 2,2-dimethylpropane-1,3-diyl diisocyanide and to investigate the effect of counter-ions on the polymeric structure of (2,2-dimethylpropane-1,3-diyl diisocyanide)silver(I) complexes, the title polymeric compound, [AgI(C(7)H(10)N(2))](n), was synthesized by treatment of 2,2-dimethylpropane-1,3-diyl diisocyanide with AgI. X-ray powder diffraction studies show, as expected, a polymeric structure, similar to the very recently reported Cl(-) and NO(3)(-) analogues [AgX(C(7)H(10)N(2))](n) (X = Cl(-) or NO(3)(-)). In the title structure, the Ag(I) centre is bridged to two adjacent Ag(I) neighbours by bidentate 2,2-dimethylpropane-1,3-diyl diisocyanide ligands via the NC groups to form [Ag{CNCH(2)C(CH(3))(2)CH(2)NC}](n) chains. The iodide counter-ions crosslink the Ag(I) centres of the chains to form a two-dimensional polymeric {[Ag{CNCH(2)C(CH(3))(2)CH(2)NC}]I}(n) network. This study also shows that this bidentate ligand forms similar polymeric structures on treatment with AgX, regardless of the nature of the counter-ion X(-), and also has a strong tendency to form polymeric complexes rather than dimeric or trimeric ones.

Key indicators: powder X-ray study; T = 298 K; mean (C-C) = 0.020 Å; R factor = 0.016; wR factor = 0.021; data-to-parameter ratio = 35.4.The title compound, C 16 H 12 N 2 , was investigated in a powder diffraction study and its structure refined utilizing the Rietveld Method. The molecule has approximate C2 symmetry. The dihedral angle between the rings is 25.6 (7) . The crystal packing is consolidated by weak C-HÁ Á ÁC N hydrogenbond-like contacts, which lead to the formation of a threedimensional network. Further stabilization of the crystal structure is achived by weak non-covalent -interactions between aromatic rings, with a centroid-centroid distance of 3.839 (8) Å . Related literature

“…In the same manner to the polymeric structure of Cl -, Iand NO 3analogues, the CNCH 2 C(CH 3 ) 2 CH 2 NC in the complex just behaves as bis-monodentate and the chelate behaviour is completely absent. This is undoubtedly expected for steric reason as the distance between the two isocyanide groups in the CNCH 2 C(CH 3 ) 2 CH 2 NC molecule are relatively too short to allow chelate complexing (Chemin et al, 1996) (Fig.2).…”

In the title compound, [AgBr(C7H10N2)]n, adjacent Ag(I) atoms are bridged by bidentate CNCH2C(CH3)2CH2NC ligands via the NC groups, forming [Ag{CNCH2C(CH3)2CH2NC}]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 {[AgI(CNCH2C(CH3)2CH2NC)]Br}n extending parallel to (010). The polymeric structure is similar to that of the very recently reported Cl−, I− and NO3 − analogues. This gives a strong indication that 2,2-dimethylpropane-1,3-diyl diisocyanide is a potential ligand for giving polymeric structures on treatment with AgX (X = Cl−, Br−, I− or NO3 −) regardless of the counter-anion used.
