Synthesis, Structural Isomerism, and Magnetism of the Coordination Polymers [M(dca)2pyz], M=Mn, Fe, Co, Ni and Zn, dca=Dicyanamide (N(CN) −2), and pyz=Pyrazine

catena-Poly[[dicyanamido(5,5′-dimethyl-2,2′-bipyridine-κ2N,N′)copper(II)]-μ-dicyanamido-κ2N1:N5]

“…Dicyanamide complexes have attracted much interest in recent years as a new class of magnetic materials, especially in the form of M II [N(CN) 2 ] 2 (M is Ni, Co, Cu or Zn) (Batten et al, 1998;Jensen et al, 2001;Kohout et al, 2000;Manson et al, 1998Manson et al, , 1999Miller & Manson, 2001). The X-ray structures of a number of compounds containing the dicyanamide anion and copper (II) have been reported (Potoc Ïn Ï a  k et al, 2001;Riggio et al, 2001;Martõ Ân et al, 2001).…”

Dicyanamide Ionic Liquids: A Versatile Precursor System for Advanced Mesoporous Materials and Functional Composites

“…[3][4][5][6][7][8] Furthermore its behavior as bridging ligand has raised major interest in the field of coordination chemistry. 24 Not only binary complexes of transition metals, such as Ni(dca) 2 or Co(dca) 2 , 25 but also coligands containing structures [26][27][28] and anionic dicyanamido metallates 29-31 that are completed by cation templation have been reported. In our studies we intended to exploit this and create a highly versatile precursor system: dicyanamido metallate anions with NHP as amphiphilic countercations.…”

Metal‐Organic Frameworks: Interpenetration and Entanglement

“…In, for example, the structures of α-[M(dca) 2 (pyrazine)], M = Mn, Fe, Co, Ni, Cu, Zn pairs of α-Po nets interpenetrate such that each boxlike cavity is catenated with eight cavities of the other net ( Figure 12a). 40, 41 Again, α-Po is a self-dual net, and this is the usual mode of interpenetration observed. In the structure of [Mn(bpea)(H 2 O) 4 ](ClO 4 ) 2 (bpea) 4 , bpea = 1,4-bis(4-pyridyl)ethane, however, each cube is catenated with 10 others from the interpenetrating net (Figure 12b).…”
