Abstract

The structure of bis[2,3-bis(thiophen-2-yl)pyrido[3,4-b]pyrazine]silver(I) perchlorate methanol disolvate is monoclinic. The Ag atom coordinates pyrido N atoms and is two-coordinate; however, the Ag atom has nearby O atoms that can be assumed to be weakly bonding – one from the perchlorate anion and one from the methanol solvate. One of the thienyl groups of a 2,3-bis(thiophen-2-yl)pyrido[3,4-b]pyrazine is flipped disordered and was refined to occupancies of 68.4 (6) and 31.6 (6)%.

The title compound, [Ag(C₁₅H₉N₃S₂)₂]ClO₄·2CH₃OH, is monoclinic. The Ag^I atom is coordinated by pyrido N atoms and is two-coordinate; however, the Ag^I atom has nearby O atoms that can be assumed to be weakly bonded – one from the perchlorate anion and one from the methanol solvate molecule. One of the thienyl groups on a 2,3-bis(thiophen-2-yl)pyrido[3,4-b]pyrazine is flipped disordered and was refined to occupancies of 68.4 (6) and 31.6 (6)%.

双[2,3-双-(硫酚-2-基)吡啶并[3,4-b]吡嗪]-高氯酸银(I)甲醇二溶液。

标题化合物[Ag(C15H9N3S2)2]ClO4-2CH3OH 呈单斜型。AgI 原子由吡啶 N 原子配位，是二配位原子；不过，AgI 原子附近的 O 原子可以认为是弱键，一个来自高氯酸盐阴离子，一个来自甲醇溶剂分子。在 2,3-双（硫代-苯-2-基）吡啶并[3,4-b]吡嗪上的一个噻吩基团是无序翻转的，精制后的占位率分别为 68.4 (6) % 和 31.6 (6)%。
