摘要:
The title compound has been prepared from MnI2 and excess diacetone alcohol (4-hydroxy-4-methyl-2-pentanon) to give brown single crystals which were suitable for a crystal structure determination. Space group P2(1)/c, Z = 4, lattice dimensions at 157 K: a = 1158.3(1), b = 1806.0(1), c = 1846.5(2) pm, beta = 97.421(8)degrees, R-1 = 0.0381. The structure consists of [Mn(DAA)(3)](2+) ions with distorted octahedral environment of the manganese atom, tetrahedral [MnI4](2-) ions and a diacetone alcohol molecule which is connected by two hydrogen bridges with the complex cation.
