Two-dimensional coordination compounds based on Fe(II) and Co(III) hexacyanometallates with Cu(II)(dien) groups: Structures and magnetic properties

Catalyst displacement assay: a supramolecular approach for the design of smart latent catalysts for pollutant monitoring and removal

“…19 A mixture of K 4 [Fe II (CN) 6 ] (1.00 g, 2.37 mmol) and Cu II (dien)Cl 2 (0.56 g, 2.37 mmol) was stirred in a water/methanol mixture (1 : 1 v/v, 25 mL) at room temperature overnight. The green precipitate obtained by filtration was washed with deionized (DI) water and acetone, and then air-dried.…”

A novel tetrazolate- and cyanide-bridged three-dimensional heterometallic coordination polymer: crystal structure, thermal stability and magnetic properties

“…Meanwhile, it is also an environmentally friendly source of cyanide because of the slow release of cyanide under hydrothermal conditions. And secondly, the cyanide group is a versatile ligand that can coordinate via monodentate or bridging modes to generate interesting complexes (Tanase & Reedijk, 2006;Shao & Yu, 2014;Mondal et al, 2001;Keene et al, 2011;Sima & Zhang, 2011;Qin et al, 2013Qin et al, , 2016. In this context, tetrazole (Htta) can exist as anionic tetrazolate (tta) when it loses an H atom at higher temperature, which may direct the formation of cationic Cu II -tetrazolate aggregates (Yao et al, 2008).…”

Synthesis, crystal structure and magnetic properties of a two-dimensional cyanide-based heterometallic coordination polymer with cationic piperazinium ligands: poly[aquatetra-μ2-cyanido-κ8C:N-dicyanido-κ2C-(piperazinium-κN4)cobalt(III)copper(II)]

“…It is well known that hexacyanidometallate, [Co(CN) 6 ] 3À , is a good building block for the assembly of multidimensional architectures. The cyanide groups can partly or fully participate in the formation of coordination bonds with various metal ions to generate diverse structures, including clusters, one-dimensional chains, two-dimensional layers and three-dimensional frameworks (Tanase & Reedijk, 2006;Shao & Yu, 2014;Mondal et al, 2001;Keene et al, 2011;Sima & Zhang, 2011). However, the further development of cyanide-bridged complex systems is obstructed by the limited availability of cationic assembled units of the general formula [ML x (H 2 O) m ] n+ (M is a divalent transition-metal ion and L is a polydentate ligand, such as a polyamine, a Schiff base or a macrocyclic ligand) (Nemec et al, 2011;Samanta et al, 2007;Qin et al, 2013).…”
