1 Source of material

The 10 mL of Cu(ClO4)2·6H2O (116 mg, 0.5 mmol) and 4-vinylpyridine (105 mg, 1.0 mmol) ethanol solution was added to a 10 mL aqueous solution of sodium dicyanamide (89 mg, 1 mmol) with severely stirring at 80 °C. The mixture was stirred for 10 min and then cooled to room temperature. After few minutes, green flaky crystals were collected, washed by ethanol, and dried in air, yield 60% (based on 4-vinylpyridine).

2 Experimental details

The structure was solved by Direct Methods and refined by full-matrix least-squares method on F 2 with anisotropic thermal parameters for all non-hydrogen atoms. The hydrogen atom positions were determined by theoretical calculations and refined with an isotropic displacement factor.

3 Comment

Metal-based coordination polymers have attracted much attention in the fields of coordination chemistry and crystal engineering. Nitrogen-containing organic ligands containing unsaturated groups have been used to assemble hypergolic fuels due to their unique activities. Moreover, high-energy dicandiamine ions (DCA) also have great advantages in regulating the structure and properties of compounds. In this work, we present a 1D coordination polymer based on 4-vinylpyridine and DCA [3], [4], [5], [6], [7], [8], [9], [10], [11].

The title crystal structure belongs to the triclinic space group P 1 ‾ (no. 2), and features a 1D chain. Each asymmetric unit contains half a Cu(II) atom, a bridging dicyanamide anion and a 4-vinylpyridine. The Cu1 atom is six-coordinated by two nitrogen atoms (N4, N4#3) from two 4-vinylpyridine ligands and four nitrogen atoms (N3#2, N1, N3#4, N1#3) from four dicyanamide anions, forming a distorted octahedral geometry with the Cu–N distances being in the normal range of 2.013(3)–2.456(4) Å. Each dicyanamide anion displays a μ2-coordination style (see the figure) to link the neighboring Cu(II) atom to form an infinite 1D chain with a Cu(II) ⋯ Cu(II) distance of 7.3783(5) Å along the b-axis. The N–Cu–N angles vary from 88.11(11) to 180.0°. These values match with the previously reported Cu(II) compounds. Furthermore, these chains are stacked via van der Waals forces to produce a 3D supramolecular structure along the b-axis.
