Crystalline and molecular structure of diaminoguanidinium tetrachlorozincate

Intermolecular interaction energies and magnetic properties of spin-isolated multinuclear CuII complexes

“…Transition metal coordination compounds with 3,5-dinitrobenzoate (DNB) have been widely studied and the ability of this ligand to coordinate in different modes involving the carboxylate and nitro groups has been recognized (Jassal et al, 2015;Hö kelek et al, 1998;Abdullah et al, 2010;Sinha et al, 2014;Miminoshvili et al, 2006). The use of a variety of coligands has resulted in structural and electronic modifications of DNB complexes that present multiple applications in fields such as magnetism, catalysis and photoluminescence (Valigura et al, 2017;Wang et al, 2013a;Paul et al, 2018;Lephoto et al, 2016;Dey et al, 2013).…”

Extraction and complexation of copper(II) with para-tert-butylbenzhydrazide and its N′,N′-dimethyl derivative

“…It is known that hydrazides and N',N'-dialkylhydrazides coordinate metals by the oxygen and terminal nitrogen atoms, forming a five-membered metallocycle [13,14]. The structure of the resulting charged and uncharged complexes can be represented by the following general formulas: Table 3.…”
