The reaction of 15-crown-5 with K2 [Ni (i-mnt) 2] {i-mnt = isobunedienileldithiol anion, [S2C2 (CN) 2] 2-} [K (15-C-5) 2] 2 [Ni (i-mnt) 2] · 2H2O (1) Structural analysis was performed by elemental analysis, infrared spectroscopy, and X-ray single crystal diffraction. The complex is triclinic, space group P-1. Crystal structure data: a = 1.2674 (5) nm, b = 1.6317 (7) nm, c = 1.7771 (7) nm, α = 102.397 (7) °, β = 104.828 ) °, V = 3.442 (2) nm3Z = 2, F (000) = 1412, R1 = 0.0727, wR2 = 0.1283. The [Ni (i-mnt) 2] group in the formula (1) is bonded to the potassium atom in two [K (15-C-5) 2] groups through the nitrogen atom of the ligand i-mnt to form Stable neutral complex.
