From the reaction of CuICN with conc-NH4OH, a host-guest type 3D network complex , [[CuII(NH3)4(H2O)](H2O)@[CuI3(CN)5]]n was isolated and characterised. A unique cationic complex guest [CuII(NH3)4(H2O)]2+ is encapsulated in the anionic host cage [CuI3(CN)5]2-.

The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the n...

Herein the examination of transformation alkynes by low-coordinate iron silylamides is presented. An anionic linear iron(I) ([Fe(N{Dipp}SiR3)2]−; Dipp=2,6-di-iso-propylphenyl, R=Me) acts as precatalyst for cyclotrimerization diphenyl acetylene but unable to transform internal with aliphatic substituents or terminal accordingly. For a benzylic, alkyne, however, 1,3-H-shift alkyne observed and pr...

In the title complex, [Pd(CH(3)COO)(2)(C(10)H(9)N(3))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment by two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and two O atoms from two anionic acetate ligands. The dpa ligand coordinates the Pd(II) atom in a boat conformation of the resulting chelate ring; the dihedral angle between the pyrid...

The anions of PdCl(2)L(2) and Pd(OAc)(2), precursors of palladium(0) used in cross-coupling and Heck reactions, play a crucial role in these reactions. Tricoordinated anionic complexes Pd(0)L(2)Cl(-) and Pd(0)L(2)(OAc)(-) are the effective catalysts instead of the usually postulated Pd(0)L(2) complex. The anion ligated to the palladium(0) affects the kinetics of the oxidative addition to ArI as...
