摘要
Cobalt orotate trihydrate, [CO(C5N2O4H2)]center dot 3H(2)O, has been synthesized and its crystal structure determined. The title compound crystallizes in the orthorhombic space group P2(1)2(1)2(1) (no. 19) with a = 771.5(2), b = 788.9(7), c = 1470.4(2) pm, and Z = 4. Bridging orotate anions coordinate in a mono- and bidentate manner to the Co atom resulting in infinite chains of alternating Co(II) cations and orotate (OrH(2-)) anions parallel to the c axis. The distorted octahedral Co coordination geometry is completed by three H2O molecules. The FT-Raman and FT-IR spectra of the crystalline compound have been recorded and an assignment of the vibrational modes is proposed. The thermal behavior (TG) was investigated.
