A series of six-coordinated Ni(II) complexes, with the general formula Ni(Xan)L2 (where Xan = = isoamyldithiocarbonato and L = 2-bromopyridine, 3-bromopyridine, 4-acetylpyridine, 3-hydroxypyridine and 2-methoxypyridine) are synthesized and characterized by the elemental analysis and various physicochemical techniques such as magnetic susceptibility and conductivity measurements, UV-visible and infrared
一系列六配位的 Ni(II) 配合物,通式为 Ni(Xan)L2(其中 Xan = = 异戊基二硫代碳酸根,L = 2-溴吡啶、3-溴吡啶、4-乙酰吡啶、3-羟基吡啶和 2-甲氧基吡啶)通过元素分析和各种物理化学技术(如磁化率和电导率测量、紫外-可见光和红外光谱数据)合成和表征。基于电子谱和磁化率测量,提出了所有配合物的八面体几何结构。红外光谱数据表明,在所有这些配合物中,取代的吡啶通过占据第五和第六轴位置的氮原子与金属离子配位,而 O-烷基二硫代碳酸酯作为单阴离子双齿配体并占据八面体结构的平面位置。通过单晶 X 射线衍射法阐明了与 3-溴吡啶的加合物的结构。配合物在三斜空间群 P-1 中结晶,晶胞参数 a = 6.5855(4) Å, b = 9.4984(6) Å, c = 12.4518(8) Å, α = 87.944(5)°, β = 78.843 (5)°,γ = 77.794(5)°。分子间的

New mercury(II) complexes of the form [PhHg(L)] (L = L1 (1), L2 (2), L3' (3), L4 = (4)); [Hg(L)(2)] (L= L5 (5), L4 (7) and [Hg-2(L6)(4)] (6) have been synthesized and characterized by micro analysis and X-ray crystallography. Both 1 and 2 are linear; complex 2 revealed intramolecular Hg center dot center dot center dot O bonding interactions. Complex 3 possesses T-shaped geometry in a linear polymeric chain motif. Although serendipitously formed, 3 is the first example of a metal trithioxanthate complex. 4 is a typical dimer and in 5, a helical chain motif is generated via Hg center dot center dot center dot S contacts. 6 is a dinuclear complex with distorted square pyramidal geometry. 7 is mononuclear with a tetrahedrally coordinated mercury(II) ion. All complexes are luminescent in solution and solid state. In 2 the nature of Hg center dot center dot center dot O interactions have been assessed by OFT calculations and the electronic transitions in 3 have been corroborated by TDDFT calculations.
