Hydrogen bond directed crystal engineering of nickel complexes: the effect of ligand methyl substituents on supramolecular structure

Reactivity of Thiosemicarbazides with Redox Active Metal Ions: Controlled Formation of Coordination Complexes versus Heterocyclic Compounds

“…This lack of investigation is particularly true for N(3)-substituted compounds, although there are some reports on Cu, Ni, Zn and Pt complexes. [45][46][47][48] In this paper we report the reaction pathways for PhNHCSNHNMe 2 with copper and tin salts, and show that the selection of the appropriate reaction conditions permits control of the product formed. A range of new heterocyclic derivatives are reported.…”

Synthesis and X‐ray structure of two conformational isomers of [Zn(medpt)(SCN)2], medpt = bis (3 – aminopropyl)methylamine

“…The relatively rigid structures of metal-amine chelate rings and capacity of the ligand for hydrogen bonding make these molecules important for stabilisation of supramolecular structures [3]. In recent years, zinc complexes of different N-and O-donor ligands have been studied due to their application as models for Zncontaining active sites in enzymes [4].…”

Transition metal complexes with thiosemicarbazide-based ligands. XLIV. The supramolecular arrangement in the Ni(II) complexes of S-methylisothiosemicarbazide

“…This complementary hydrogen bonding could be considered as a starting interaction in the processes of selfassembly of bis(TSC) and bis(N-substituted TSC) metal complexes with dicarboxylate [1].…”

“…According to the numerous reports, bis(thiosemicarbazide) metal complexes appeared to be very good candidates for these kinds of structures, since their adducts with different dicarboxylate anions exhibit a variety of crystalline architectures [1][2][3][4][5][6][7][8]12]. Namely, thiosemicarbazide (TSC), N 1 H 2 -N 2 H-C 3 (@S)-N 4 H 2 , behaves as a bidentate ligand coordinated through the terminal N 1 and S atoms, the remaining N atoms (the hydrazine N 2 and thioamide N 4 ) form the hydrogen bonding donor pair, suitably oriented for the interaction with the acceptor pair, i.e.…”
