摘要：
Complex beta-(Bu3NH)(4)Mo8O26 has been transformed from alpha-(Bu4N)(4)Mo8O26 in the presence of o-mercaptophenol (H(2)mp) and CuCl2 in MeOH, and structurally characterized. It can be considered as a dimer [(Bu3NH)(2)Mo4O13](2) with a center of symmetry. Each molybdenum atom is in a severely distorted octahedral environment. Two types of H bond between the cations and the anions have been found in the complex: N-H ... O and C-H ... O, which may play important roles in the alpha-->beta transformation, (C) 1999 Elsevier Science Ltd. All rights reserved.
