Abstract

C 28 H 28 CuN 6 O 16 , triclinic, P¯ , (no. 2), a = 7.3118 (7)

Crystal structure of catena-poly[tetrakis(μ2-trifluoroacetato-κ2 O:O′)(μ2-2,5-dimethylpyrazine-κ2 N,N′)dicopper(II)], C7H4CuF6NO4

“…The coordination plane comprising Cu1, O3, C3, O4 and Cu1A make a dihedral angle of 46.77°w ith the plane formed by the DMP ligand. The Cu-N distance is 2.1522(15) Å that is similar to a previously described structure [17]. The bond lengths of Cu1-O1, Cu1-O2A, Cu1-O3, Cu1-O4A are 1.9659(15) Å, 1.9770(15) Å, 1.9697(15) Å and 1.9795(15) Å, respectively, that fall within the normal range [18].…”
