cze	Tvorba supramolekulárních vodíkových vazebných řetězců a sítí z halogenobenzoátů měďnatých s N-methylnikotinamidem: Supramolekulární izomerismus	Byla zkoumána samoskladba supramolekulárních struktur z komplexů halogenobenzoátu mědi (11) obsahujících N-methylnikotinamidový ligand. Následující strukturní sloučeniny a polymorfní struktury byly stanoveny rentgenovou strukturní analýzou monokrystalu - sloučeniny [Cu (4-Fbz) (2) (mna) (2) (H2O)], [Cu (4-Clbz) (2) ) (mna) (2) (H2O)], [Cu (4-Brbz) (2) (mna) (2) (H2O)], dva polymorfy [Cu (2,6-Cl (2) bz) ( 2) (mna) (2) (H2O) (2)] středová tečka 2H (2) O, [Cu (3,5-Cl (2) bz) (2) (mna) (2) (H20) (2) )] středová tečka 2H (2) O, [Cu (3-Fbz) (2) (mna) (2) (H20) (2)] středová tečka 2H (2) O a [Cu (3-Clbz) ( 2) (mna) (2) (H2O) (2)] středový bod 2H (2) O, dva polymorfy centra [Cu (3-Brbz) (2) (mna) (2) (H2O) (2)] tečka 2H (2) O, [Cu (3-Ibz) (2) (mna) (2) (H20) (2)] středová tečka 2H (2) O, [Cu (2,5-Cl (2) bz) ) (2) (mna) (2) (H2O) (2)] středová tečka 2H (2) O, [Cu (2,3-Cl (2) bz) (2) (mna) (2) (H20) (2)] středový bod H2O, [Cu (2,6-Cl (2) bz) (2) (mna) (2) (H2O)] středový bod 2H (2) O, [Cu (3,4-Cl) (2) bz) (2) (mna) (2) (H20)] středová tečka 2H (2) O, [Cu (3-Brbz) (2) (mna) (2) (H20)] a [Cu ( 2-Fbz) (2) (mna) (2) (mu-H20)] (n), (mna = N-methylnikotinamid, 4-Fbz = 4-fluorbenzoát, 4-Clbz = 4-chlorbenzoát, 4-Brbz = 4-brombenzoát, 3-Fbz = 3-fluorbenzoát, 3-Clbz = 3-chlorbenzoát, 3-Brbz = 3-brombenzoát, 3-lbz = 3-jodbenzoát, 2-lbz = 2-jodbenzoát, 2,3-Cl (2) bz = 2,3-dichlorbenzoát, 2,5-Cl (2) bz = 2,5-dichlorbenzoát, 2,6-Cl (2) bz = 2,6-dichlorbenzoát, 3,4-Cl (2) bz = 3,4-dichlorbenzoát a 3,5-Cl (2) bz = 3, 5-dichlorbenzoát). Sloučeniny jsou monomerní komplexy s deformovanou oktaedrální nebo čtvercovou pyramidální koordinační koulí kolem iontu Cu2 +. Dvě sady polymorfů [Cu (2,6-Cl (2) bz) (2) (mna) (2) (H2O) (2)] 2H (2) O a [Cu (3-Brbz) ( 2) (mna) (2) (H2O) (2)] 2H (2) O jsou dva příklady koordinačních sloučenin, které jsou konformační a supramolekulární izomery. Krystalová struktura komplexu [Cu (4-Fbz) (2) (mna) (2) (H2O)] ukazuje fázový přechod ve dvou teplotách.

eng	Formation of supramolecular hydrogen-bonding chains and networks from copper (II) halogenobenzoates with N-methylnicotinamide: Supramolecular isomerism	The self-assembly of supramolecular structures from copper (11) halogenobenzoate complexes containing N-methylnicotinamide ligand have been explored. The following compound and polymorph structures were determined by single-crystal X-ray structural analysis-the compounds [Cu(4-Fbz)(2)(mna)(2)(H2O)], [Cu(4-Clbz)(2)(mna)(2)(H2O)], [Cu(4-Brbz)(2)(mna)(2)(H2O)], two polymorphs of [Cu(2,6-Cl(2)bz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, [Cu(3,5-Cl(2)bz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, [Cu(3-Fbz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, and [Cu(3-Clbz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, two polymorphs of [Cu(3-Brbz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, [Cu(3-Ibz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, [Cu(2,5-Cl(2)bz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O, [Cu(2,3-Cl(2)bz)(2)(mna)(2)(H2O)(2)]center dot H2O, [Cu (2,6-Cl(2)bz)(2)(mna)(2)(H2O)]center dot 2H(2)O, [Cu(3,4-Cl(2)bz)(2)(mna)(2)(H2O)]center dot 2H(2)O, [Cu(3-Brbz)(2)(mna)(2)(H2O)] and [Cu (2-Fbz)(2)(mna)(2)(mu-H2O)](n), (mna = N-methylnicotinamide, 4-Fbz = 4-fluorobenzoate, 4-Clbz = 4-chlorobenzoate, 4-Brbz = 4-bromobenzoate, 3-Fbz = 3-fluorobenzoate, 3-Clbz = 3-chlorobenzoate, 3-Brbz = 3-bromobenzoate, 3-lbz = 3-iodobenzoate, 2-lbz = 2-iodobenzoate, 2,3-Cl(2)bz = 2,3-dichlorobenzoate, 2,5-Cl(2)bz = 2,5-dichlorobenzoate, 2,6-Cl(2)bz = 2,6-dichlorobenzoate, 3,4-Cl(2)bz = 3,4-dichlorobenzoate and 3,5-Cl(2)bz = 3,5-dichlorobenzoate). The compounds are monomeric complexes with a distorted octahedral or square-pyramidal coordination sphere around Cu2+ ion. The two polymorph sets of [Cu(2,6-Cl(2)bz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O and [Cu(3-Brbz)(2)(mna)(2)(H2O)(2)]center dot 2H(2)O are two examples of coordination compounds which are conformation and supramolecular isomers. The crystal structure of complex [Cu(4-Fbz)(2)(mna)(2)(H2O)] shows the phase transition in two temperatures. The compound [Cu (2-Fbz)(2)(mna)(2)(mu-H2O)In is a coordination polymer with bridging aqua ligand.
