Abstract

The novel coordination polymer [Co₄(TCAS)(μ₄- SO₄)(4,4′-Hbipy)₂]_n (TCAS = the octaanion of p-sulfonatothiacalix[4]arene) (1) has been synthesized hydrothermally and characterized. X-ray diffraction analyses reveal a two-dimensional (2D) layer structure built from the [Co₄(TCAS)(μ₄-SO ₄)]²-unit. The tetranuclear cobalt(II) clusters bridged by the μ₄-SO₄^2- and phenoxy groups of the same TCAS provide a unique trapeziform magnetic mode; magnetic studies in the temperature range 2-300 K show weak antiferromagnetic interactions between the four cobalt(II) centers.
