This paper systematically summarizes the domestic and international Ⅰ B, Ⅱ B group metal organic selenium ligand complex progress of the cluster (with) this kind of complex synthesis, structural characterization and analysis of test methods reviewed; synthesized and characterized. several new metal selenium clusters (with) complexes to study its performance. and single-crystal X-ray diffraction analysis, infrared spectroscopy, 1 H-NMR spectroscopy and differential thermal gravimetric analysis were used to characterize. The results showed that the coordination structure of the complex plane triangular structure, the selenium atoms phenol by three benzene selenium and mercury atoms coordinated to form a slightly deformed the complex belongs to the monoclinic system, space group P2 1 / n, with unit cell parameters: α = 9.724 (2) nm, b = 17.319 (4) nm, C = 2.1771 (5) nm, β = 95.357 (5) °, Dc = 1.685g/cm 3 , V = 3.6504 (14) nm 3 , Z = 4, R 1 = 0.0432, w R 2 = 0.1167 2. HgBr 2 and PPh 3 PhSeH in room temperature for the synthesis of a class the adamantane structure of mercury - selenium multicore analysis, infrared spectroscopy, 1 H-NMR spectroscopy and differential thermal gravimetric analysis were used to characterize. The results show that the complex is triclinic, space group P-1, with unit cell parameters: a = 1.37322 (11) nm, b = 1.47879 (12) nm, c = 2.26406 (18) nm, and α = 73.095 (2 ) °, β = 73.579 (2) °, γ = 65.783 (1) °, D c = 1.839g/cm 3 , V = 3.9409 (6) nm < sup> 3 , Z = 4, R 1 = 0.0319, w R 2 = 0.0707. 4 Hg atoms and phenylselenyl phenol 4 Se atoms in the molecule constitute a class adamantane structure. Of. AgNO 3 and PPh the 3 PhSeH reaction at room temperature synthesis of a novel structure of selenium, phosphorus dual-core silver complexes [Ag 2 < analysis to characterize. The results show that the complex is triclinic, space group P-1, with unit cell parameters: a = 1.10749 (6) nm, b = 1.34572 (7) nm, c = 2.05010 (11) nm α = 80.666 (1 ) °, β = 86.561 (2) °, γ = 72.516
