Synthesis and Structure of Triphenylbismuth Dinitrite and Dinitrate

Triphenylbismuth dinitrate (I) and triphenylbismuth dinitrite (II) were synthesized through the reaction of triphenylbismuth dichloride with silver nitrate in an acetone–alcohol (1 : 1) solution or with sodium nitrite in acetone–water (1 : 1) solution. According to X-ray diffraction data, bismuth atoms in Iand II have a distorted trigonal bipyramidal configuration. The intramolecular Bi···N(1,2) contacts in II (2.997(3), 2.982(4) Å) are shorter than similar contacts in I(3.038(3), 3.031(3) Å); the Bi···O(2,4) distances in II and Bi···O(2,5) distances in I are equal to 2.879(2), 2.913(3) and 2.893(3), 2.896(3) Å, respectively.
