| الوصف: | The new compounds Ni 2 (tren) 3 (M O₂ O 2 S 6 ) 2 · 2.75 H 2 O (I) and C O₂ (tren) 3 (MoS 4 ) 2 (II) (tren = tris(2-aminoethyl)amine) were prepared under solvothermal conditions. The structure of I is built up of one-dimensional [Ni 2 (tren) 3 ] n 4+ chains and isolated [M O₂ O 2 S 6 ] 2- anions. Each Ni atom in the cationic chain is surrounded by six N-atoms to form a distorted octahedron. The connection of the Ni-atoms in the [Ni 2 (tren) 3 ] n 4+ -units with the tren molecules leads to zigzag chains in the (100) plane. The situation is different for compound II which consists of isolated [C O₂ (tren) 3 ] 4+ cations and discrete tetrahedral [M O S 4 ] 2- anions. The Co atom in the cation is in a distorted trigonal bipyramidal environment of four N atoms of one tren molecule and of one N atom from a bridging tren-molecule, building up the dimeric structure of the [C O₂ (tren) 3 ] 4+ unit. Between the anions and cations of both compounds hydrogen bonding is observed. The thermal behaviour of I and II was investigated using differential thermoanalysis and thermogravimetry. On heating I first looses the crystal water and then decomposes slowly in one step, whereas II decomposes also in one step, but at a significantly lower temperature. |
