双核体

RAPD analysis indicated that the profiles of mycelial protoplasts obtained from same single spore isolates amplified by 10 random primers were entirely identical, corroborating that the two nuclei of a basidiospore were homogeneous.

RAPD分析显示，源于同一单孢分离物的菌丝原生质体为10个随机引物所扩增的图谱彼此完全相同，印证了担孢子中的双核是同质的。

This dissertation divides into seven chapters and the main contents and conclusions are listed as following:1. Three series binuclear lanthanide carboxylate coordination polymers 1～7 have been synthesized under hydrothermal conditions by altering the length of carbon chains between carboxyl group and phenyl ring on ligands, which are isophthalic acid, 1,3-phenylenediacetic acid and 1,3-phenoxydiacetic acid, and lanthanide ions such as Pr~(3+), Eu~(3+)and Ho~(3+).

论文共分七章，主要研究内容和结论如下：1、通过改变间苯二甲酸配体的羧基和苯环之间的碳链长度，从间苯二甲酸、间苯二乙酸到间苯二氧乙酸，以及改变稀土离子半径Pr~(3+、Eu~(3+)和Ho~(3+)出发，在水热条件下制备了三个系列双核金属单元的稀土羧酸二维配位聚合物1～7。

Furthermore, the structures of the complexes are strange. The tripodal ligand H〓L〓 form a 2: 2 ring-like binuclear complexes [Eu〓·L〓·6DMF] ·CH〓OH·DMF with Eu〓 in DMF. Two DMF molecules are accommodated in the ring and coordinate with Eu〓.

此外配合物的结构还比较特殊，三足配体H〓L〓与铕的配合物在配位能力较强的溶剂DMF中形成环状的2：2型双核配合物[Eu〓。L〓·6DMF]·CH〓OH·DMF，环状空腔刚好能够把两个配位的DMF溶剂分子包在里面。

Three kinds of small molecular copper and zinc superoxide dismutase mimics were synthesized with N, N-bis (benzimidazol-2-ylmethyl) amine (N3), N, N-bis (benzimidazol-2-ylmethyl) methylamine(MN3) and N,N-bis (benzimidazol-2-ylmethyl) benzylamine(BN3) as ligands. The com-plexes were characterized by UV, IR and element analysis and the structures were proposed.

Both iron atoms of the binuclear unit are bridged by one oxy atom and two acetate groups. Each iron atom is also bound to facially - coordinating tridentate IDB ligand with the aliphatic nitrogen donor situated trans to theμ- oxy atom. Each iron centers is in a distorted octahedral symmetry.

每个双核单元的两个铁原子均通过一个氧原子和两个醋酸根连接，每个铁原子同时还与位于桥氧原子对位的三齿配体IDB重脂肪链上氮原子相结合，每个铁中心为一变形八面体结构。

With two tripodal ligands, dtma and tmpa, dtma=diethylenetriamine-N'-acetate and tmpa=tris(2-pyridyl-methylamine and a polyamine ligand, trien (=triethylenetetramine), serving as terminal ligands, we synthesized 19 species of new imidazolate -bridged Cu-Zn, Zn-Zn and Cu-Cu, and other relating compounds, in which 〓 and 〓 complexes are model compounds of Cu, Zn-SOD.
