{2,2'-[N,N'-Bis(pyridin-2-ylmeth-yl)propane-1,3-diyldi(nitrilo)]di-acetato}-cobalt(III) hexa-fluoridophosphate aceto-nitrile 0.064-solvate.

ABSTRACT: In the title compound, [Co(C19H22N4O4)]PF6·0.064CH3CN, commonly known as [Co(bppd)]PF6·0.064CH3CN, where bppd represents the historical ligand name N,N'-bis(2-pyridylmethyl)-1,3-diaminopropane-N,N'-diacetate, the Co(III) atom is coordinated in a distorted octa-hedral geometry with an N4O2 donor atom set. The acetate O atoms, which exhibit monodentate coordination, are oriented in a trans configuration with respect to each other, whereas the pyridyl N atoms are coordinated in a cis configuration. The compound crystallizes with two crystallographically unique cations and two anions per asymmetric unit along with a disordered, partially occupied (occupancy = 0.128) aceto-nitrile solvent mol-ecule. Crystals of the title complex were found to be twinned by pseudomerohedry with a 180° rotation around [10-1] and a refined contribution of 90.5?(3)% of the major twin component.
