cze komplexy mědi- konformace jejich polymorfů a sekvence supramolekulového uspořádání hodíkových vazeb Nové měďnaté X-salicylové komplexy s N,N-diethylnicotinamidem (dena) [Cu2)(dena)(2)(H2O)(2)] (RCOO = 3-methylsalicylatový anion (3-Mesal,1), 4-methylsalicylatový anion (4-Mesal,2), 5-methylsalicylatový anion (5-Mesal,3), 5-methoxysalicylatový anion (5-MeOsal,4) nebo 4-methoxysalicylatový anion (4-MeOsal,5)), a komplex [Cual)(2)(dena)(2)(H2O)(2)]a (TM) 2H (3-MeOsal = 3-methoxysalicylatový anion (6)) byly připraveny v krystalickém stavu a charakterizovány spektroskopickými metodami (IR, Vis- UV, EPR). U všech sloučenin podle jejich složení (1-5) bylo koordinační okolí atomu mědi určeno jako oktaedr. Komplex 1 byl připraven ve dvou různých formách. Rentgenové rozbory z komplexů 1, 4, a 5 byly uskutečněny a odhalily tetragonálně-bipyramidální okolí atomů Cu. komplexy mědi;krystalová struktura;vodíkové vazby;polymorfy
eng [Cu(X-salicylato)2(N,N-diethylnicotinamide)2(H2O)2] Complexes: Conformational Polymorphism and its Consequence in Supramolecular Hydrogen-bonding Networks Formation Novel copper(II) X-salicylate complexes with N,N-diethylnicotinamide (dena) of the formula [Cu(RCOO)(2)(dena)(2)(H2O)(2)] (RCOO = 3-methylsalicylate anion (3-Mesal, 1), 4-methylsalicylate anion (4-Mesal, 2), 5-methylsalicylate anion (5-Mesal, 3), 5-methoxysalicylate anion (5-MeOsal, 4) or 4-methoxysalicylate anion (4-MeOsal, 5)), and complex [Cu(3-MeOsal)(2)(dena)(2)(H2O)(2)]a (TM) 2H(2)O (3-MeOsal = 3-methoxysalicylate anion (6)) have been prepared in the crystalline forms and characterized by spectroscopic methods (IR, Vis-UV, EPR). All the compounds according to their composition (1-5) seem to possess octahedral copper(II) stereochemistry. The complex 1 has been prepared in two different forms. X-ray analyses of the complexes 1, 4, and 5 were carried out and they featured a tetragonal-bipyramidal geometry around the copper atoms...
