Abstract

The crystal structure of [Co(NH3)(6)](ADC)(HADC) center dot 2 H2O (1) (ADC(2-) = acetylenedicarboxylate) (P2(1)/n, Z = 4) was mistakenly described as containing the [Co(H2O)(6)](3+) ion [I. Stein, U. Ruschewitz, Z. Nattuforsch. 2011, 66b, 471-478]. A revision is reported. While attempting to reproduce 1, we isolated phase-pure crystalline material of [Co(NH3)(6)]Cl-2(HADC) center dot H2O (2), the crystal structure of which was also reported in the article above. Upon standing in the aqueous mother liquor at room temperature for several days, the needle-shaped crystals of 2 disappear, while block-shaped crystals of the formerly unknown compound [Co(NH3)(6)](ADC)(HADC) (3) grow. Satellite peaks in the X-ray diffraction frames indicate that the crystal structure is incommensurately modulated. Dissolving crystals of 3 in water at elevated temperature leads to plate-shaped crystals of the new compound [Co(NH3)(6)](2) (ADC)(3) center dot 3 H2O (4) upon slow cooling to room temperature. Compounds 2-4 were investigated by elemental analysis, powder X-ray diffraction and infrared spectroscopy. Structural characterization of 4 by single-crystal X-ray analysis was also achieved (P (1) over bar, Z = 2). Complex 1, however, could not be reproduced.
