The Crystal Structure of Succinonitrilo-disilver Nitrate, 2AgNO3·NC(CH2)2CN

Abstract
The structure of 2AgNO3·NC(CH2)2CN has been determined by X-ray analysis. It is mono-clinic; a=5.87, b=17.79, c=4.61 Å, β=118.2°, space group P21a, two formula units in the cell. The structure is essentially ionic and consists of the complex cations, [AgNC(CH2)2CNAg]2+ (Ag–N, 1.97 Å), and the nitrate anions. All the bond lengths are normal. The molecule of succinonitrile was found to take the trans configuration; this is in conformity with the conclusion drawn from the infrared study.
