n
(II), where Piv—is the pivalate anion, L
1 is pyrazine, and L
2 is pyrimidine, result in new heterometallic polymers {Li2Co2(Piv)6(L

n
(IV), and Li2Co2(Piv)6(L

n
(V). The resulting compounds contain tetra-nuclear {Li2Co2(Piv)6} fragments connected by neutral bridging ligands (pyrazine or pyrimidine) into layer structures. Crystal structures III–V are determined, and the magnetic properties of III and IV are studied. |
