• W2023252389 abstract "The reaction system composed of triethanolamine (TEA) and tetrathiovanadate in the presence of MeONa (MeOLi) or NaNH2 was studied to afford vanadium and alkali metal TEA complexes. Complexes [M subsetV6O6[N(CH2CH2O)2(CH2CH2OH)]6]2S6 (M = Na (1), Li (2)) contain two cyclic V((IV)) [12]metallacrown-6 cations linked by a polysulfide S6(2-) anion. Also separated from the reaction system is a novel sodium TEA complex [[Na(TEA)]2S6]n (3), in which parallel coordination chains [Na(TEA)+]n are connected by O-H...S hydrogen bonds forming 3-D network structure. Variable-temperature conductance of 3 was determined to display semiconductor feature. The desulfurization of VS4(3-) was observed to form S6(2-) anion and/or S8 molecule in the synthetic reactions of 1-3. A striking contrast was noted that MoS4(2-) did not desulfurize in the similar reaction to that of VS4(3-) with TEA, and a Na/TEA complex containing MoS4(2-), (Et4N)2[Na2(mu-TEA)2(CH3OH)2](MoS4)2 (4), was obtained instead. The S...H-O and O...H-O hydrogen bonds play an important role in forming the one- or three-dimensional structures for all these complexes by the linkages between clusters and chains. The IR spectrum indicates the structural similarity of complexes 1 and 2. For complex 4, the Mo=S stretch vibration at 468 cm(-1) showing widening and slight red-shift and the slight movement of the 1H NMR signals of TEA ligand to downfield are considered to be the influence of the S...H-O hydrogen bonds. Variable temperature magnetic susceptibility data were collected for complex 1. The effect magnetic moment per V6 unit varies gradually from 4.04 muB at 300 K to 6.24 muB at 5 K, exhibiting ferromagnetic interaction. Heisenberg-type vector-coupling model and molecular field approximation were used to treat the interaction between the paramagnetic sites and gave a good fitting result: J = 3.97 cm(-1), J' = 1.99 cm(-1), g = 1.99, F = 3.64 x 10(-3). Density functional calculation was also performed to complex 1 and its Li, K analogues. The lowest total bonding energy of -874.001 eV was obtained for [Na subsetV6(mu3-O)6] complex containing six unpaired electrons, indicating the stability of a V6 system with six independent spins S = 1/2. When the alkali metal ion is inserted into the [V6(mu3-O)6] cavity, the positive values of the bonding interaction (E(b)) indicate that the insertion depresses the total energy and that complexes 1 and 2 together with K+ complex may exist. However, the lowest E(b) value of the K+ complex implies its instability." @default.
