Synthesis and Crystal Structure of a Novel Six-Coordinate Gallium (III) Complex

چکیده [English]

The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where pyda is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group P < /em>ī and two molecules per unit cell. The unit cell parameters are a=10.238(2) Å, b=10.428(2) Å, c=13.838(2) Å, α=70.375(3)°, β=77.938(3)°, γ=64.120(3)°. The structure has been refined to a final value for the crystallographic R factor of 0.0579 based on 4703 reflections with I > 2σ(I).
