Hydrogen-bonded coordination network in crystal structures of [Cu(3-PM)₄Cl₂] and [Cu(4-PM)₄Cl]Cl, (PM = pyridylmethanol)

Synthesis, crystal structures and properties of Ni(NCS)2-4-(hydroxymethyl)pyridine coordination compounds

“…In this context it is noted that no thiocyanato coordination compounds with this ligand are reported. Anyhow, a few coordination compounds with different anionic ligands are reported in the CCDC and some selected examples are given in the reference list [61][62][63][64][65][66]. In most of them this ligand does not act as bridging ligand and is coordinated only with the N atom to the metal center.…”

Polymeric and monomeric dipicolinate complexes with 4-hydroxymethyl pyridine: spectral, structural, thermal and electrochemical characterization

“…In this way, both dpc and 4-hymp ligand connects copper(II) ions to form an extended 3-D polymeric structure. 4 Cl]Cl [26]. It is the first time we have observed that the 4-hymp acts as a bridging ligand between the metal ions.…”

“…4) (6) O1-Cu1-N2: 100.51 (7) O2-Cu1-N2: 98.22 (7) N1-Cu1-N2: 175.62 (8) N1-Cu1-O5: 86.21 (7) N2-Cu1-O5: 89.74 (7) O3 i -Cu1-N2: 86.32 (7) O5-Cu1-O3 i : 169.05 (6) O1-Cu1-O3 i : 87.96 (7) N1-Cu1-O3 i : 97.96 (7) Hydrogen (2), the 4-hymp does not act as a bridging ligand between the nickel(II) ions. Generally, the 4-hymp is coordinated to metal ions through the nitrogen atom, forming the mononuclear metal complexes [23][24][25][26][27].…”

“…On the other hand, 4-hydroxymethyl pyridine is a drug metabolite of ethionamide and isofamide, these drugs of second-line therapy are used for the treatment of multidrug-resistant tuberculosis [22]. Only a few structures of metal complexes with 4-hydroxymethyl pyridine have been reported [23][24][25][26][27].…”
