A Genuine Example of a Discrete Bimetallic (Cu, Gd) Complex:  Structural Determination and Magnetic Properties

The LCuGd(NO3)3·Me2CO complex crystallizes in the monoclinic space group P21/c (No. 14) in a cell having the dimensions a = 9.799(1) Å, b = 18.926(3) Å, c = 16.012(1) Å, β = 96.530(8)°, Z = 4. The four units forming the unit cell do not display any obvious short contacts between them. The magnetic behavior is characteristic of a ferromagnetic interaction between the Gd3+ and Cu2+ ions.
