| Popis: | [M(C5H5NCOO)3(H2O)2][Cr(NCS)6] · nH2O complexes, where M = La and n = 2 (1) or M = Nd and n = 1 (2), were synthesized by reacting M(NO3)3 (M = La, Nd, K3[Cr(NCS)6]) and nicotinic acid (C5H5NCOO) in aqueous solution. Their structure was established by IR spectroscopy and X-ray diffraction analysis. The crystals of complexes 1 and 2 are monoclinic, space group P21/n, Z = 2; for complex 1, a = 9.66800(10) A, b = 25.7662(2) A, c = 15.4843(2) A, β = 106.4700(10)sO, V = 3698.99(7) A3, ρcalcd = 1.761 g/cm3; for complex 2, a = 9.53120(10) A, b = 25.5166(4) A, c = 15.3843(3) A, β = 104.9450(10)sO, V = 3614.96(10) A3, ρcalcd = 1.779 g/cm3. Different hydrate compositions of the given compounds may be due to the specific features of intermolecular interactions in their structures. |
