✦ Synopsis

One of the most rapidly expanding areas of coordination chemistry research is the design of magnetic materials based on molecular building blocks. [1] A perusal of the literature reveals that a successful design strategy for preparing molecular magnets is the coordination of organic radicals such as nitronyl nitroxides [2] and organocyanides such as TCNE À C (tetracyanoethylene) [3] and TCNQ À C (7,7,8,8-tetracyanoquinodimethane) [4] to paramagnetic transition metal ions. The presence of both metal spins (typically S > 1/2) and organic spin carriers (S = 1/2) leads to strong local super-[

Single crystals of Lu(ClO 4 ) 3 ´3 H 2 O were obtained by slow dehydration of Lu(ClO 4 ) 3 ´6 H 2 O at 140 °C under flowing argon. The compound crystallizes in the triclinic crystal system (P1, Z = 2, a = 750.3(1), b = 838.4(1), c = 1054.6(2) pm, a = 79.77(2)°, b = 79.18(2), c = 63.83(2), R all = 0.
