N2 - Double complex salts [Ln(C 6 H 5 NO 2 ) 3 (H 2 O) 2 ][Cr(NCS) 6 ] · 2H 2 O, Ln = Lu (I), Ce (II), Y (III), have been synthesized by the reaction between aqueous solutions of Ln(NO 3 ) 3 (Ln = Lu, Ce, Y), K 3 [Cr(NCS) 6 ], and nicotinic acid (C 5 H 5 NCOO). The salts representing light lilac crystalline powders have been studied by chemical analysis, IR spectroscopy, and single-crystal X-ray diffraction. The salts crystallize in monoclinic system, space group P2 1 /n, Z = 4: a = 9.4969(15) Å, b = 25.606(4) Å, c = 15.541(2) Å, β = 107.126(4)°, V = 3624.34 Å 3 , ρ calcd = 1.864 g/cm 3 for I; a = 9.6559(2) Å, b = 25.8492(5) Å, c = 15.5303(3) Å, β = 106.586(1)°, V = 3715.0(1) Å 3 , ρ calcd = 1.756 g/cm 3 for II; and a = 9.5662(7) Å, b = 25.756(2) Å, c = 15.541(1) Å, β = 107.122(2)°, V = 3659.3(4) Å 3 , ρ calcd = 1.690 g/cm 3 for III. The cations in the crystal structures of complexes I–III have a chain polymer structure, and the coordination polyhedron of chromium(III) represents a slightly distorted octahedron. The steric factor has no appreciable effect on the specific features of the crystal structures in the series of lanthanide hexa(isothiocyanato)chromate(III) complexes with nicotinic acid, and the content of crystallization water molecules is varied alone in their composition.
