Hydrothermal Synthesis and Characterization of [V_(16)O_(38)(Cl)][Cu(enMe)_2]_(3.5) · 2H_2O Containing {V_(16)O_(38)} Cluster

摘要

Compound [V_(16)O_(38)(Cl)][Cu(enMe)_2]_(3.5) · 2H_2O(1) has been hydrothermally synthesized and characterized by means of single-crystal X-ray diffraction, elemental analysis, IR, EPR and TGA analysis. The X-ray crystallography shows that compound 1 contains a new {V_(16)O_(38)} cluster shell, which is connected by [Cu(enMe)_2]~(2+) coordination fragments into a 3-D framework. The compound crystallized in a monoclinic system with space group P2(1), M = 2235. 82, a = 1. 26076(3) nm, b = 2.55802(6) nm, c = 2. 14742(4) nm, β=90. 7380(10)°, V = 6. 9250(3) nm~3, Z = 4, F(000) = 4418, D_c = 2.145 g · cm~(-3), μ = 3.227 mm~(-1), (Δ/σ) = 0. 000, S = 1. 066.
