Synthesis and structure of a new one-dimensional cobalt complex with dicyanamide and 4-picolyl choride bridges

The synthesis and structure of the 1D cobalt (II) complex, [Co(L)2(dca)2] (1) (dca = dicyanamide, C2N3–, L = 4-picolyl choride) is reported. Complex 1 crystallized in triclinic system, space group P -1, with cell dimensions of a = 7.291(2) A, b = 7.481(2) A, c = 9.007(3) A, α =104.444(4)°, β = 96.971(4)°, γ =102.618(4)°, V = 456.1(2) A3, Z = 1, Dc = 1.624 Mg/m3. In complex 1, Co (II) is 6-coordinated by N atoms of four dca ligands and two L ligands. The centrosymmetric CoN6 chromophore is an axially elongated octahedron that has Co-N distances ranging from 2.122(3) to 2.154(3) A. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
