| الوصف: | Reactions of Mn(NCS) 2 with 3-bromopyridine in acetonitrile lead to the formation of Mn(NCS) 2 (3-bromopyridine) 4 ( 1 ) and Mn(NCS) 2 (3-bromopyridine) 2 (MeCN) 2 ( 2 ) that were characterized by single crystal X-ray diffraction. Compounds 1 and 2 consist of discrete complexes, in which the Mn(II) cations are octahedrally coordinated by two trans -N-bonding thiocyanate anions and four pyridine ( 1 ) or two pyridine and two acetonitrile ligands ( 2 ). Thermoanalytical measurements on 1 and 2 have shown that upon heating half of the 3-bromopyridine co-ligands from 1 or both acetonitrile ligands from 2 are removed leading to a crystalline phase with the composition [Mn(NCS) 2 (3-bromopyridine) 2 ] n ( 3-II ). From dry n-butanol a phase with the same composition was obtained ( 3-I ) that corresponds to a polymorphic or isomeric form of 3-II . Crystal structure analysis of 3-I shows that in this form the Mn cations are linked by pairs of anionic ligands into linear chains. The results of magnetic measurements on 3-I show antiferromagnetic interactions along the chains and the analysis of the magnetic susceptibility using the Fisher model for chains gave a J value of −5.76(5) K. |
