Abstract

C 42H32MnN10S6,t riclinic, P1 (no. 2), a =9.666(1) Å, b =11.077(2) Å, c =11.352(2) Å, a =87.663(2)°, Source of materialManganese(II) acetate tetrahydrate (0.123 g, 0.5 mmol) and NH 4 SCN (0.076 g, 1mmol) were refluxed in anhydrous methanol (10 mL) for 50 min, then were simultaneously added 20 mL methanol solution of freshly distilled salicylaldehyde and ethylenediamine at molar ratio 2:1.The mixture was stirred for 5h,4,4'-bipyridyl sulfide (0.11 g, 0.5 mmol) was added, the pH value was adjusted to 5with CH 3COOH solution, and the mixture was further stirred for 2h,then filtered. The resulting clear solution was diffused with diethyl ether vapor at room temperature for three weeks, yellow crystals were collected by filtration and dried in air (yield 0.156 g, 37 %

Manganese(II) complexes of 5-(4-pyridyl), 5-phenyl and 5-(4-methoxy-phenyl)-1,3,4-oxadiazole-2-thione containing 2, 2′-bipyridyl/ethylenediamine: synthesis, spectral, and X-ray characterization

“…The nitrogens of uncoordinated bipy present in the structure are associated through intermolecular hydrogen bonding with the CH hydrogen of the 4-pytone ligand. The geometry and bonding parameters within the bpy molecule agree with those of other bpy complexes [32,33]. In addition, complex 1 is stabilized by weak pÁÁÁp interactions occurring between pyridine (Cg py ) and 1,3,4-oxadiazole (Cg oxa ) rings from a nearby molecule with a distance of 3.701 Å (Fig.…”
