Nickel(II) and copper(II) complexes with triethylenetetraaminehexaacetic acid: From binuclear complex to 1D coordination polymer

Three-Dimensional 3d−4f Polymers Containing Heterometallic Rings: Syntheses, Structures, and Magnetic Properties

“…In this paper, two novel 3D complexes [Ln(H 2 O) 4 ][Ni 2 TTHA(SCN) 2 ]·H 3 O + (Ln = Pr, Ce) focused on Ni−Ln heteronuclear complexes were synthesized based on a binuclear building block of [Ni 2 (H 2 O) 2 (H 2 TTHA)] . These complexes were obtained stepwise: (a) synthesis of binuclear unit [Ni 2 (H 2 O) 2 (H 2 TTHA)]; (b) reactions of binuclear complexes Ni 2 TTHA and LnCl 3 .…”

Two novel 3D 3d–4f polymers with triethylenetetraaminehexaacetic acid: Syntheses, structures, and magnetic properties

“…In this paper, we report the syntheses, crystal structures and magnetic properties of two novel 3D 3d-4f complexes Single crystals suitable for X-ray analysis for all complexes were obtained by the method described as follows: an aqueous solution (10 cm 3 ) of MCl 2 AE 6H 2 O (M = Ni(1), Cu(2)) (2 mmol) was added to the suspension of TTHA (1 mmol, 496 mg) of 10 cm 3 water (The binuclear unit [Ni 2 (H 2 O) 2 (H 2 TTHA)] [15] and [Cu 2 (H 2 O) 2 (H 2 TTHA)] [16] have been obtained, X-ray crystallographic files in CIF format for which have been placed in Supplementary material). After 30 min, an aqueous solution (10 cm 3 ) of LaCl 3 AE 6H 2 O (1 mmol, 0.0353 mg) and KSCN (2 mmol,196 mg) for about 1 h, the solution was transferred to an ethanol environment.…”
