Reactions of manganese(II) pivalate, benzoate, and cymantrenecarboxylate with 3,5-dimethylpirazole (Hdmpz) have been found to result in mononuclear complexes (Hdmpz)4Mn(OOCR) where R = But and Ph, respectively, and binuclear complex {Mn(μ-OOCC5H4Mn(CO)3)(OOCC5H4Mn(CO)3) (Hdmpz)2(OH2)}2 which contains a pyrazole solvate molecule. The obtained complexes have been isolated in high yields as single crystals and have been characterized by chemical analysis, IR spectroscopy, and X-ray diffraction.

MnII and CoII salts reacting with 4-(4-carboxyphenyl)-4,2′:6′,4″-terpyridine (4-Hcptpy) in DMF/H2O afford two complexes, [Mn(4-cptpy)(DMF)(H2O) 2]n·n(4-cptpy)·nDMF (1) and [Co(4-cptpy)2(H2O)2]n (2). Complex 1 is a 1D ribbon coordination polymer assembled by Mn2 dimer and tridentate 4-cptpy ligand. The guest 4-cptpy anion is embedded in 3D supramolecular architecture with strong hydrogen bonds. Complex 2 is a 1D linear chain coordination polymer with quadrangled pores. The complex 1 releases H2O and DMF in 87-150 C, and the anhydrous [Mn(4-cptpy)] n·n(4-cptpy) remains thermally stable until 403 C. Variable temperature magnetic susceptibility study in 2-300 K proves that a weak antiferromagnetic interaction exists in the (μ-O2CR) 2Mn2 core.
Manganese clusters derived from 2-pyridylcyanoxime: New topologies and a large spin ground state in pyridyloximate chemistry

, p. 12334 - 12345 (2013/09/02)
Series of manganese clusters derived from 2-pyridylcyanoxime with Mn 3II (1), Mn4II (2a, b), Mn II4MnIII4 (3), MnII 2MnIII6MnIV2 (4) and MnII3MnIII6MnIV (5) cores have been characterized. Dc magnetic measurements reveal antiferromagnetic coupling for 1-4 and dominant ferromagnetic interactions for 5 which shows the largest ground state reported to date in pyridyloximate chemistry (S = 14).
