✦ Synopsis


Tetra(n-butyl)ammonium nitrite reacts with ‘dichlorophthalocyaninatoruthenium(III) acid’ to yield bis(tetra(n-butyl)ammonium) bisnitrophthalocyaninatoruthenate(II). It crystallizes monoclinic with crystal data: a = 15.114(4) Å, b = 22.34(3) Å, c = 18.206 (11) Å, β = 90.88(5)°; space group P1 21/n 1, Z = 4, and its X-ray crystal structure has been determined. Ru is located in the centre of the slightly distorted phthalocyaninate dianion, and is coordinated to two nitrite ions through their nitrogen (N) atoms in a staggered trans-configuration. The average Ru - N ~p~ ( Np pyrrolic N atoms) and Ru -N distance is 1.978(6) and 2.068(5) Å, respectively. The electrochemical and spectroscopic properties (IR, resonance Raman, UV/vis) of the compound are in full agreement with its molecular structure.
