Chloro­[η⁵-1-(dimethyl­amino­eth­yl)inden­yl](triphenyl­phosphine)nickel(II) dieth­yl ether hemisolvate

The title complex, [Ni(C₁₃H₁₆N)Cl(C₁₈H₁₅P)]·0.5C₄H₁₀O, consists of an Ni^II center coordinated by a dimethyl­amino­eth­yl-substituted inden­yl ligand, a triphenylphosphine ligand and a chloride ion. The asymmetric unit includes two very similar mol­ecules that show only small conformational differences in the inden­yl side chain.

catena-Poly[[silver(I)-μ₂-1,1′-dimethyl-2,2′-biimidazole-κN³:N^3′] nitrate 1.167-hydrate methanol 0.33-solvate]

The title structure, {[Ag(C₈H₁₀N₄)]NO₃·1.167H₂O·0.33CH₄O}_n, consists of helical chains in which approximately linearly coordinated Ag atoms alternate with bridging 1,1′-dimethyl-2,2′-biimidazole ligands in a syn conformation. The environment of each Ag atom is completed by weak Ag—O bonds to a bidentate nitrate ion.
