摘要：

A new hexanuclear copper(II) complex with the formula Cu-6(II)(bdmap)(3)Cl-6(O)(OH) (1; bdmap = 1,3-bis-(dimethylamino)-2-propanolato) has been synthesized and characterized structurally. Compound 1 has a propeller structure with an approximate C-3 symmetry. There are two possible diastereomers for this compound, and only one of them has been identified structurally, regardless the synthetic routes. The core structure of 1 consisting of six copper(II) ions and five oxygen atoms resembles that of cryptand. A proton is trapped inside this inorganic ''cryptand''. Crystal data for 1, C21H52CU6Cl6O5N6: monoclinic, space group P2(1)/n, a = 12.691(7) Angstrom, b = 16.31(1) Angstrom, c = 20.45(2) Angstrom, beta = 107.07(5)degrees, V = 4047(5) Angstrom(3), Z = 4. Magnetic susceptibility measurements at variable temperatures and an H-1 NMR study in solution established that compound 1 has an antiferromagnetically coupled ground state.
