Аннотация

Double ionic complexes [M(C5H5NCOO)3(H2O)2][Cr(NCS)6] · nH2O, where M = Eu (I), n = 1.15; Dy (II), Er (III), n = 1.5; M = Yb (IV), n = 2, have been synthesized by the reaction between M(NO3)3, M = Eu, Dy, Er, Yb, K3[Cr(NCS)6], and nicotinic acid (C5H5NCOO) in an aqueous solution and studied by chemical analysis, IR spectroscopy, and X-ray diffraction. Crystals of complexes I–IV are monoclinic, space group P21/n, Z = 4; a = 9.5358(2) Å, b = 25.4871(5) Å, c = 15.4303(4) Å, β = 105.513(1)°, V = 3613.6(1) Å3, ρcalcd = 1.799 g/cm3 for I, a = 9.5901(5) Å, b = 25.8599(15) Å, c = 15.6316(9) Å, β = 106.829(2)°, V = 3710.6(4) Å3, ρcalcd = 1.782 g/cm3 for II, a = 9.5640(3) Å, b = 25.8936(11) Å, c = 15.6498(7) Å, β = 106.895(2)°, V = 3708.3(3) Å3, ρcalcd = 1.791 g/cm3 for III, and a = 9.5049(2) Å, b = 25.6378(4) Å, c = 15.5120(3) Å, β = 106.934(1)°, V = 3616.1(1) Å3, ρcalcd = 1.864 g/cm3 for IV.
