- Abstract
Abstract A new ion-pair complex, 1-methyl-3-benzylimidazolium bis(maleonitrile-dithiolato) nickelate(II), has been synthesized and characterized by IR spectroscopy, UV-visible spectroscopy and X-ray crystallography. The crystallographic data for the complex: triclinic <img src="/fulltext-image.asp?format=htmlnonpaginated&src=U277272P682P1GTG_html\10870_2005_Article_2215_TeX2GIFIEq1.gif" border="0" alt="$$\bar 1$$" />, a = 8.415(1) Å, b = 9.924(1) Å, c = 11.333(2) Å, a = 114.11(1)°, ß = 102.46(1)°, ? = 100.88(1)°, V = 801.8(2) Å3, Z = 1. The molecular packing pattern showed a completely separated column stacking for cations and anions of the complex along with the b-axis. The anion is not completely planar. The five-membered nickel-containing rings are slightly puckered. The cation, [BzIm]+, adopts a conformation where the benzene ring and imidazole ring twisted with the reference plane C10–C11–N3.
