| Abstract: | The crystals of the complex of azacrown (2,2) with Eu(NO3)3 are monoclinic sys-tem with space group P21/n and parameters of unit cell a=16.2745(18), b=11.5237(25),c=12.5658(60)Å, β=112.180(34)°, Z=4.The diffraction data were collected on the Nico-let XRD R3 four-circle diffractometer using MoKα radiation. Its structure was solved by heavy-atom method. The structure parameters were refined by means of block-diagonal matrix least-square method, R=0.042. The coordination number of the europium ion is ten. The europium ion is in the mean plane of the ring and linked to 4 oxygen atoms,2 nitrogen atoms of the crown and 2 nitrates forming cation part of the complex. Two nitrates are localized in each side of the crown ring. |
