Buckled-layered Structure of Zinc Dicyanamide, Zn^II[N(CN)₂]₂

Abstract

The reaction of dicyanamide and Zn(II) leads to Zn[N(CN)2]2, which has a new structure type, namely, a buckled-layer, noninterpenetrating motif.

Self‐Assembly of Five Cadmium(II) Coordination Polymers from 4,4′‐Diaminodiphenylmethane

“…[19] To the best of our knowledge, such a [Cd 4 (µ (3-Py-CONH 2 ϭ nicotinamide). [20c] As shown in Figure 5 (c), the [Cd(µ 1,1 -dca-N,N) 2 ] n layers are further linked by the dadpm ligands into an α-P o -like 3D net as in [Mn(dca) 2 (pz)].…”

Phase Transition of a Dicyanamide with Rutile‐like Structure: Syntheses and Crystal Structures of α‐ and β‐Cd[N(CN)2]2

“…Surprisingly, during the detailed investigations of the divalent dicyanamides a phase transition only was observed for Zn[N(CN) 2 ] 2 [13,14]: Orthorhombic β-Zn[N(CN) 2 ] 2 (space group: Pnma) reversibly transforms into the hightemperature polymorph α-Zn[N(CN) 2 ] 2 (space group: Cmcm) at about 215 K. Contrarily, none of the intensively studied dicyanamides M II [N(CN) 2 ] 2 (M ϭ Mg, Cr, Mn, Co, Ni, Cu), which crystallize analogously to rutile, seems to show any phase transition. Köhler [15], Jensen [14], and Miller [2] et al reported about αand β-Co[N(CN) 2 ] 2 , however these two compounds have been synthesized by quite different syntheses, and they do not exhibit a reversible transition induced by temperature or pressure.…”

Tailoring structure and magnetic properties of NixCo1−x(N(CN)2)2 molecular magnets

“…The inset shows the entire measured spectra. All spectra show typical characteristic of well-known dicyanamide-metal complexes [15,31,32], with strong stretches (n CN ) around 2271 cm À1 and 2205 cm À1 . With increasing Ni content, the peak position shifts to higher wavenumbers, which implies a larger force constant between the C and N atoms and an increase of the electronic density on the corresponding chemical bond.…”
