Template synthesis in the nickel(II)–thiocarbohydrazide–propanone triple system

“…As previously [1][2][3][4][5] the kinetics of complexing processes designed by the D H ¼ f(C F , C L o , t) relationships (D H is the absorbance of the metal chelate GIM, corresponding to the concentration of Ni 2 [Fe(CN) 6 ] in a GIM (C F , mol dm -3 ), concentration of corresponding ligand in solution in contact with GIM (C o L , mol dm -3 ) and the complexing process time (t, min) are given. They were analysed by a procedure already described [8].…”

“…is observed, whereas peaks at 389. 2 These circumstances provide evidence favouring that several coordination compounds are formed in the nickel(II)-thiocarbohydrazide-propanone, also. It should be noted especially that when propanone was absent from the reactionary mixture, the substance isolated from it at the end of chemical process, showed only peak M ¼ 592 c.u.…”

“…I.r. spectra of S H 3 C-C-CH 3 H 2 N-HN-C-NH-NH 2 (at 1560 and 1565 cm );1 , respectively) and m(SAC@N) (at 2125 cm )1 ). The m(SAC@N) and m(C@N) bands are absent in the i.r.…”

“…Previously [1][2][3][4], complexing processes in the nickel(II)-dithiooxamide-methanal, nickel(II)-dithiooxamideglyoxal and nickel(II)-dithiooxamide-propanone proceeding upon contact of nickel(II)hexacyanoferrate(II) gelatin-immobilized matrix materials (GIM) with wateralkaline solutions containing the organic compounds indicated, at room temperature. It has been shown that dithiooxamide is one of the ligand synthons of lowtemperature template synthesis.…”

Gelatin-immobilized metal complexes: synthesis and applications

“…The details of nucleophilic substitution in the metal hexacyanoferrate(II) matrices in the specific 3d-metal ion-ligand systems have been discussed [55,57]. The possibility of complexation in f-metal hexacyanoferrate(II) gelatin-immobilized matrices, i.e., in (UO 2 ) 2 [Fe(CN) 6 ] matrix, was shown with participation of certain 8-hydroxy-and 8-mercaptoquinolines [144][145][146][147]. The data indicate that the interaction of the dioxouranyl(VI) ion with the respective ligand is preceded by destruction of (UO 2 ) 2 [Fe(CN) 6 ] under action of OH À ; however, these data are not sufficient to make more substantiated conclusions.…”
