Cyano-bridged bimetallic complexes based on nitroprusside [Fe(CN)5(NO)]2− and [Cu(TAAB-macrocycle)]2+: Synthesis, structure and thermal stability

Cyano-bridged polynuclear coordination compounds derived from paramagnetic [Mn(H2daptsc)]2+ and photochromic [Fe(CN)5NO]2− building blocks

Metal complexes with H₂daptsc ligand were first used as building blocks to create polynuclear multifunctional materials.

Syntheses, structures and magnetic properties of cyano-bridged one-dimensional Ln3+–Fe3+ (Ln = La, Dy, Ho and Yb) coordination polymers

Four new heterometallic one-dimensional coordination polymers with formulae trans-[La(o-phen)₃(H₂O)(μ-CN)₂Fe(CN)₄]·7H₂O (1) and trans-[Ln(H₂O)₂(phen)₂(μ-CN)₂Fe(CN)₄]·nH₂O [Ln/n = Dy/8 (2), Ho/7 (3) and Yb/7 (4), (o-phen = 1,10-phenanthroline)] have been synthesized.

The first photochromic bimetallic assemblies based on Mn(iii) and Mn(ii) Schiff-base (salpn, dapsc) complexes and pentacyanonitrosylferrate

The bimetallic cyano-bridged complexes demonstrating photochromism and magnetism were obtained and studied.

Voltammetric Study of the Copper Pentacyanonitrosylferrate Adsorbed on the Silica Modified with a Poly(propylene)imine Hexadecylamine Dendrimer for Determination of Nitrite

Poly(propylene)imine hexadecylamine dendrimer (DAB-Am-16) was anchored on the surface of 3-chloropropylsilyl silica gel and subsequently interacted with copper nitroprusside. The composite was characterized by infrared (FTIR), energy dispersive X-ray (EDX), and cyclic voltammetry. The above techniques confirmed the successful anchoring of the dendrimer on the silica gel modified surface and its interaction with copper nitroprusside. The cyclic voltammogram of CuNPSD was found to exhibit two redox couples with (Eθ′)1= 0.30 V and (Eθ′)2= 0.78 V versus Ag/AgCl ( mol L−1;  mV s−1) attributed to the redox processes and , respectively. The CuNPSD-modified graphite paste electrode was found to show a linear response of to  mol L−1for nitrite determination with a detection limit (DL) of  mol L−1and an amperometric sensitivity of 25.0 mA/mol L−1. The CuNPSD-modified graphite paste electrode was found to show a good electrochemical stability and an excellent response to the electrocatalytic oxidation of sodium nitrite.
