PzH], Pz
− = pyrazolate anion, PzH = pyrazole, C3H4N2 is obtained by the reaction of ytterbium metal with pyrazole in liquid ammonia and subsequent increase of the temperature
to 200°C resulting in the formation of colorless single crystals of the compound. The X-ray single crystal analysis reveals
that the structure consists of 2
∞Yb2(NH2)2(Pz)4] planes with neutral Yb(NH3)2(Pz)3
PzH] monomeric molecules that are located between the planes and ytterbium is trivalent. This is the first example of a two-dimensional
network structure of an organic amine of the rare earth elements that derives from an electride induced synthesis. The product
decomposes under release of ammonia outside its sealed reaction vessel, viz. if the NH3 pressure is removed. |
