Tricenter Iron(II)dicobalt(III) Complexes with Two Cyanide Bridges.

Crystal structures of two mixed-valence copper cyanide complexes with N-methyl­ethylenedi­amine

The crystal structures of two mixed-valence copper cyanide compounds involving N-methyl-ethylenedi-amine (meen), are described. In compound (I), poly[bis(μ3-cyanido-κ3C:C:N)tris(μ2-cyanido-κ2C:N)bis(N-methylethane-1,2-di-amine-κ2N,N')tricopper(I)copper(II)], [Cu4(CN)5(C3H10N2)2] or Cu4(CN)5meen2, cyanide groups link CuI atoms into a three-dimensional network containing open channels parallel to...

Bent thorocene complexes with the cyanide, azide and hydride ligands.

Reaction of the linear thorocene with NC(-), N3(-) and H(-) led to the bent derivatives [(Cot)2Th(X)](-) (X = CN, N3) and the bimetallic [{(Cot)2Th}2(μ-H)](-), whereas only [(Cot)2U(CN)](-) could be formed from (Cot)2U.

Two-dimensional cyanide-bridged heterobimetallic complexes based on CpCoðCNÞ3 : Syntheses, structures and magnetic properties

Using the half-sandwich tricyanometalate, KCpCo(CN)3 (1, Cp = cyclopentadienyl), as the building block, two new cyano-bridged heterobimetallic complexes, [{CpCo(CN)3}2M(H2O)2] Æ 2H2O (M = Fe , 2; Co, 3), have been synthesized and structurally characterized. Complexes 2 and 3 are isostructural. In each complex, [CpCo(CN)3] acts as a bis-monodentate bridging ligand toward the central [M(H2O)2] 2+...

precipitation chelation of cyanide complexes in electroplating industry wastewater

electroplating industry wastewater (eiw) characterized by high chemical oxygen demand (cod) is a big source of water and air contamination with heavy metals. the formation of cyanide complex with heavy metals is responsible for its elevated cod. the concentration of heavy metals in eiw can be removed by the use of different precipitating agents (sulfide and hydroxide). but the major bottleneck ...
