Redetermination of diaquabis(vanillinato-²O,O')cobalt(II)

D.-D. Lin and D.-J. Xu

Abstract: The structure of the title complex, [Co(C₈H₇O₃)₂(H₂O)₂], has been redetermined in the space group C2/c. The original report [Xiao, Lan, Zhang & Jiang (2002). Guangxi Shifan Daxue Xuebao Ziran Kexueban (J. Guangxi Normal Univ.), 20, 81-83] declared the space group to be Cc. The molecule lies on a twofold axis; the vanillinate anion chelates to the Co^II atom through the methoxy and hydroxy groups. The Co-O_methoxy bond is longer than the Co-O_hydroxy bond by 0.2673 (18) Å.
