New antiferromagnetic Mn(II) pivalate polymer: synthesis and reactivity

New manganese (II) 2d-polymer with deprotonated hydroxytetrazine bridges

“…According to the X-ray study (see [12] for details), compound 5 contains the metal carboxylate Mn 6 (O) 2 (OOCCMe 3 ) 10 core (Mn-l 4 -O 1.879(4)-2.219(5) Å , Mn-O(OOCR) 1.950(4)-2.346(5) Å ) (Fig. 5) which was observed earlier for similar compounds [8,13].…”

“…In this paper, the reactions of Mn(II) (S = 5/2) pivalate polymer [Mn(OOCCMe 3 ) 2 (EtOH)] n (1) [8] with potential ligand 3-hydroxy-6-(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine (2) are discussed.…”

Synthese eines paramagnetischen Polymers durch ringöffnende Polymerisation eines gespannten [1]Vanadoarenophans

“…[ [10] oder wurden durch eine Polykondensation synthetisiert, wobei die isolierten Materialien entweder ein geringes Molekulargewicht aufweisen, unlöslich oder unvollständig charakterisiert sind. [11] [12] Die Identität von 2 und 3 wurde durch Massenspektrometrie, Elementaranalyse und EPR-Spektroskopie eindeutig bestätigt.…”

First hexanuclear manganese(II) μ6-Cl centered carboxylate anion: Synthesis, structure and magnetic properties

“…The magnetic behavior of these molecular systems strongly depends on the geometry and electronic structure [2][3][4][5]. In a search for novel high spin metal containing systems we attempted to synthesize new manganese(II) carboxylates as precursors for ''spin material'' in molecular spintronic devices [6].…”

“…Recently, we have shown that the manganese(II) pivalate polymers [Mn 5 Cl(OH)(Piv) 8 (MeCN)(HPiv)(H 2 O)] n (1) [4] and [Mn(Piv) 2 (EtOH)] n (2) [5] can be used for the preparation of homo-and heterospin manganese polynuclear carboxylates. Here, we report on the preparation of ionic compounds containing a new hexanuclear manganese(II) pivalate anion [Mn 6 (l 6 -Cl)(Piv) 12 ] À .…”
