Abstract—The reactions of tetraphenylstibium nitrate with nitric acid and of tetraphenylstibium acetate with
acetic acid yield adducts Ph₄SbONO₂ · HNO₃ (I) and Ph₄SbOC(O)CH₃ · CHH₃COOH (II). According to X-ray
diffraction data, the antimony atom in [Ph₄Sb][O₂NO···H···ONO₂] has a tetrahedral coordination. The
CSbC bond angles and Sb–C bond lengths vary within 108.04(6)109.75(4) and 2.096(1)–2.098(1) Å,
respectively. The anion includes the intermolecular hydrogen bond O(1)H(1)···O(1)'': the O(1)–H(1),
H(1)···O(1)'', and O(1)···O(1)'' distances are 0.91(4), 1.56(4), and 2.460(2) Å, respectively; and the OHO angle
is 169(5). The nitrate groups are usually planar. Complex II also contains the intermolecular hydrogen bond
with the following parameters: O(3)–H(3), 0.92 Å; H(3)···O(2), 1.68 Å; and O(3)···O(2) 2.594 Å; the
O(2)H(3)O(3) angle is 172.1. This H-bond noticeable changes the coordination polyhedron of the antimony
atom compared to that in tetraphenylstibium acetate.
