Abstract

Heterometallic pivalate Co2Sm(Piv)7(2,4-Lut)2 (1) was prepared for the first time and structurally characterized at 293 and 160 K. Antiferromagnetic exchange interactions are dominant in complex 1. This compound experiences a first-order phase transition within 210–260 K. A set of thermodynamic functions was obtained for this complex (C p , H 0 T - H 0180 , and S 0 T ), and parameters were determined for solid-phase thermolysis where samarium cobaltate SmCoO3 is the only product.
