Anna Jurowska, Janusz Szklarzewicz, Maciej Hodorowicz, Monika Tomecka, more

Journal of Molecular Structure > 2015 > 1081 > Complete > 6-13

The reaction of N-substituted alcohols (2-aminoethanol, 3-amino-1-propanol and 2-hydroxyethylhydrazine) with K ₃ Na[Mo(CN) ₄ O ₂ ]⋅6H ₂ O in water–ethanol solution results in isolation of three new complexes of formulae: (PPh ₄ ) ₂ [Mo(CN) ₄ O(amet)]⋅3H ₂ O (1), (amet=2-aminoethanol), (PPh ₄ ) ₂ [Mo(CN) ₄ O(ampro)]⋅3H...

Synthesis, structure and properties of oxocyanido W(IV) complexes with substituted salicylaldimines of 2-aminoethanol compared to Mo(IV) analogs

Monika Tomecka, Janusz Szklarzewicz, Anna Jurowska, Andrzej Wojtczak

Polyhedron > 2014 > 81 > Complete > 81-89

A series of W(IV) complexes with 2-aminoethanol and 5-bromo-, 5-chloro-, 5-methoxy-, 3,5 -dichloro-substituted salicylaldehydes is described. The complexes were isolated and characterized by elemental analysis, IR and UV–Vis spectroscopy as well as cyclic voltammetry. The single crystal X-ray analysis of salt (PPh ₄ ) ₂ [W(CN) ₃ O(metsal)]·5H ₂ O (where metsal=Schiff...

Diverse coordination of Schiff bases based on 2-(aminomethyl)pyridine or 2-acetylpyridine at Mo(IV) centre: Synthesis, crystal structures and physicochemical properties

Anna Jurowska, Janusz Szklarzewicz, Katarzyna Kurpiewska, Monika Tomecka

Polyhedron > 2014 > 75 > Complete > 127-134

The reaction of Schiff bases formed in reaction of 2-(aminomethyl)pyridine and aliphatic ketones (acetone, dihexyl ketone, 2- and 4-heptanone) or 2-acetylpyridine and 2-aminoethanol with K ₃ Na[Mo(CN) ₄ O ₂ ]·6H ₂ O in water–ethanol solution results in isolation of two new complexes of formulae: (PPh ₄ )[Mo(CN) ₃ O(ampy)]·2H ₂ O (1) (ampy=2-(aminomethyl)pyridine)...

Nucleophically transformed N-heterocyclic nitriles trapped by cyanooxomolybdates(IV): Crystallographic and spectroscopic study

Anna Ryniewicz, Monika Tomecka, Janusz Szklarzewicz, Dariusz Matoga, more

Polyhedron > 2012 > 45 > 1 > 229-237

The reaction of K ₃ Na[Mo(CN) ₄ O ₂ ]·6H ₂ O with 2,3-dicyanopyrazine or 2-pyridinecarbonitrile in aqueous media results in isolation of two new compounds of formulae (PPh ₄ ) ₂ [Mo(CN) ₃ O(pzac)]·2H ₂ O (Hpzac=3-carbamoyl-2-pyrazinecarboxylic acid) and (PPh ₄ ) ₂ [Mo(CN) ₃ O(pynccn)]·3H ₂ O·EtOH (Hpynccn=2-pyridineiminocarbonitrile)...
