Two new complexes, [Cu(abpt) 2 (dca) 2 ] and [Co(abpt) 2 (dca) 2 ] (abpt = 4-amino-3,5-bis-(pyridin-2-yl)-1,2,4-triazole; dca = dicyanamide), have been prepared and magneto-structurally characterised.
Article
Complexes [Co(biq)(μ1,5-dca)2]n (1) and [Ni(biq)(μ1,5-dca)2]n (2) (biq is 2,2΄-biquinoline, dca is dicyanamide anion, N(CN)2–) have been characterized by crystal structure analysis, and spectral and magnetic measurements. The crystal structures of...

From Co(NO3)2·6H2O ‐ NaN3 ‐ abpt reaction system, a mononuclear complex [Co(abpt)2(N3)2] (abpt = 4‐amino‐3,5‐bis(pyridin‐2‐yl)‐1,2,4‐triazole) (1) and a dinuclear complex [Co2(abpt)(µ‐abpt‐H)2(N3)4]·1.12H2O (2) were obtained. The presence of neutral abpt, as well as azido ligands was proved by IR spectroscopy. X‐ray crystallography shows that 1 is...

From the system CuCl 2 – pbi – NaN(CN) 2⁻ , polymeric [CuCl(μ 1,5 -dca)(pbi)] n ·nH 2 O ( 1 ) complex (dca=dicyanamide, pbi=2-(2-pyridyl)benzimidazole) was isolated and characterized by structure analysis, spectral and magnetic measurements. Infrared spectroscopy confirmed the presence of pbi, dca and water molecules in 1 . Its solid-state structur...

Ionic cobalt(II) complex [Co(dcnm)(H2O)(phen)2](dcnm) (1) (dcnm = dicyanonitrosomethanide, phen = 1,10-phenantroline) has been prepared by a diffusion technique. Its structure is formed by [Co(dcnm)(H2O)(phen)2]⁺ complex cation and free dcnm counterion in the lattice which acts as a hydrogen-bond acceptor to the hydrogen bonds from the water ligand...

Two new complexes, [CoII(_bpy_)2(dca)2] (1) and [CoII(_bpy_)2(tcm)2] (2) (_bpy_ = 2,2-bipyridine, dca = dicyanamide and tcm = tricyanomethanide) were prepared as powders. During their recrystallization on air, two other new complexes, [CoIII(_bpy_)2CO3]dcg (dcg = N,N’-dicyanoguanidine, (H2N)C(NCN)2) (3) and [CoIII(_bpy_)2CO3]tcm·2H2O (4), have been...

Five Co(II)-L-X complexes, where L = 1,10-phenanthroline (phen) or 2,2′-bipyridine (bpy) and X = dicyanamide (N(CN)2−) or tricyanomethanide (C(CN)3−) anions, have been synthesized and characterized by single crystal X-ray diffraction studies. The dca and tcm anions exhibit monodentate or μ1,5-bidentate bridging modes. In two complexes, tcm acts as...

The formation and growth of lead sulfide nanocrystals in lead stearate Langmuir–Blodgett (LB) films are investigated by optical absorption spectroscopy. Kinetics of the concentration changes of lead ions in the different states formed during the growth process, as well as the evolution of the nanocrystal average size versus growth time, are studied...
