文摘

By subtly varying crystallization conditions, four distinct cadmium acetate coordination networks with unit cell formulas Cd₈₇(H₂O)₃₆(EtOH)₁₈(OH)₁₂(CH₃CO₂)₁₆₂ (1), Cd₈₇(H₂O)₇₂(OH)₁₂(CH₃CO₂)₁₆₂ (2), Cd₁₀(H₂O)₆(OH)₂(CH₃CO₂)₁₈ (3), and Cd₂₀(H₂O)₂₀(OH)₄(CH₃CO₂)₃₆ (4) have been isolated. The coordination networks exhibit interesting structural diversity and have been investigated by powder X-ray diffraction, elemental analysis, thermal gravimetric analysis, infrared spectroscopy, and single-crystal X-ray diffraction. All four complexes are composed of secondary building units with the general formula [Cd₄(OAc)₉(渭₃-OH)]^{2鈭?/sup>. Complexes 1 and 2 exhibit a remarkable three-dimensional network composed of aligned columns, each 4.5 nm long, containing three different cadmium acetate clusters. Complexes 3 and 4 extend in two-dimensions with each unit cell repeating a different linkage isomer of the [Cd₄(OAc)₉(渭₃-OH)]2鈭?/sup> cluster.}
