| Popis: | Self-assemblies of two unsymmetrical tridentate N2O/N2S donor Schiff base ligands, that is, 2-((2-(dimethylamino)ethylimino)methyl)phenol (HL1) and methyl-2-pyridylmethylidenehy-drazinecarbodithioate (HL2), with different cadmium salts have led to 11 anion-controlled complexes, namely, [Cd(Ln)2] [n = 1 for 1 and n = 2 for 2], [Cd(L1)(HL1)](ClO4) (3), [Cd(HL2)(L2)](ClO4)(H2O) (4), [Cd(L2)Cl2] (5), [Cd(L1)Cl]2 (6), [Cd(L1)(NO3)]2 (7), [Cd(L2)(NO3)(CH3OH)]2 (8), [Cd(L2)(NO3)(H2O)]2 (8a), [Cd2(L1)2(SCN)2]n (9), and [CdL2(SCN)2]n (10), respectively. Eleven compounds were characterized by elemental analyses, IR spectra, MS and thermogravimetric analyses, of which 10 structures 2, 3, 4, 5, 6, 7, 8, 8a, 9, and 10 were further determined by single-crystal X-ray diffraction analyses. The compounds 2, 3, and 4 are mononuclear, in which the neutral molecule unit CdII(L2)2 (in 2) as well as cation units [CdII(HL1−2)(L1−2)]+ (L1 for 3 and L2 for 4) are respectively connected by hydrogen bonds C−H···S, O−H···O, and C−H·... |
