摘要：
A structurally distinct, multi-copper(II)-substituted silicotungstate K3H4Cu0.5{Cu[Cu7.5Si2W16 O-60(H2O)(4)(OH)(4)](2)} center dot 9H(2)O (1) has been synthesized and characterized by FT-IR spectroscopy, elemental analysis, variable-temperature magnetic measurements, electron spin resonance, and X-ray diffraction. Green crystalline plates of 1 were obtained by the reaction of K-8[gamma-SiW10O36] center dot 12H(2)O with 8 equiv. of Cu(II) in a 50% ethylene glycol solution. A cationic copper center connects the terminal oxygen atoms of neighboring polyanions, resulting in a one-dimensional structure. Magnetic susceptibility measurements indicate weak ferromagnetic superexchange between the Jahn--Teller-distorted S=1/2 Cu(II) centers. (c) 2008 Elsevier Ltd. All rights reserved.
