Crystal structure of diiodido-bis(phenanthridine-κN)cadmium(II), CdI2(C13H9N)2, C26H18CdI2N2

Abstract

C 26 H 18 CdI 2 N 2 , monoclinic, P2 1 /c (no. 14), a = 16.805(4) Å, b = 10.693(3) Å, c = 14.737(3) Å, b = 115.24(2)°, Source of materialThe title compound was synthesized through the coordination reaction between CdI 2 and phenanthridine at 1:2 molar ratio in refluxed anhydrous ethanol solution. A mixture of CdI 2 (1.06 mmol) and phenanthridine (2.12 mmol) was dissolved in ethanol (50 ml) solution. After the mixture was stirred for 2h while being heated at reflux, the reaction solution was filtered immediately and the filtrate was cooled to room temperature to give white power (yield: 0.64 g, 82.5 %). A single crystal suitable for X-ray crystallography was obtained by recrystallization from ethanol solution. Elemental analysis found: C, 42.94 %; H, 2.55 %; N, 3.87 %; calcd. for C 26 H 18 CdI 2 N 2 (724.6): C, 43.09 %; H, 2.50 %; N, 3.87 %. Experimental detailsThe highest and lowest difference electron peaks are 1.386 and -0.578 e·Å 3 , respectively.
