Tetraorganopnictonium and Alkali Metal Salts of Pyridine‐2,6‐di‐tetrazolate

Abstract

Abstract. Alkali metal (Na, K) and tetraorganopnictonium (AsPh 4 , PPh 4 ) salts were prepared from 2,6-bis(1H-tetrazol-5-yl)pyridine (H 2 pydtz) and characterized by multinuclear NMR, IR, and UV/Vis absorption spectroscopy. Single crystal XRD of (AsPh 4 ) 2 (pydtz)·5H 2 O reveals isolated pydtz 2-dianions sandwiched between two AsPh 4 + cations and an interesting hydrogen bridging network comprising the five co-crystallized water molecules and the three pydtz N atoms. (PPh 4 ) 2 (pydtz)·5H 2 O is isostructural to (AsPh 4 ) 2 (pydtz)·5H 2 O as re-
