摘要:
Seven new copper(I) complexes containing 3-amino-5,6-dimethy1-1,2,4-triazine (ADMT), (Cu(mu-Cl)(ADMT)(PPh3)](2) (1), [Cu(mu-NCs)(ADMT)(PPh3)](2) (2), [Cu(ADMT)(PPh3)(2)Cl] (3), [Cu(ADMT)(PPh3)(2)Br] (4), [Cu(mu-Cl)(ADMT)(AsPh3)](2) (5), [Cu(mu Br)(ADMT)(AsPh3)](2) (6) and [Cu(ADMT)(AsPh3)(2)I] (7) have been synthesized by the reactions of CuX (X = Cl, Br, I, SCN) with triphenylphosphine/triphenylarsine EPh3 (E = P for 1-4; E = As for 5-7) and ADMT in mixed solvents. Complexes 1-7 have been characterized by IR, NMR, luminescence, elemental analyses and X-ray diffraction. In 1, 2, 5 and 6, the intermolecular hydrogen bonds of type I R-2(2)(8) are formed by two N-H donors and two N atoms from two ADMT ligands. In 1-7, the intramolecular hydrogen bond of type II R-1(1)(6) is formed between one N-H donor from ADMT and one halide ion. In 1, 2, 5 and 6, the halide ions and thiocyanate ions bridge two copper atoms to form the parallelogram Cu2X2, which are further linked to form infinite zigzag chains along alpha-axis through the hydrogen bond of type I R-2(2)(8).
