Daniel L. Reger, Department of Chemistry and Biochemistry, University of South Carolina at Columbia, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for his work developing new metal complexes of tris(pyrazoyl)methane (tpm) ligands. These ligands are closely related to tris(pyrazoyl)borates, but have been much more difficult to prepare. Reger has developed new synthetic pathways to tpm ligands such as HC(pz)3, HC(3,5-Me2pz)3, HC(3-Phpz)3, HC(3-tBupz)3 and HC(3-iPrpz)3. Linked bi- and poly-functional pyrazoyl methane ligands, such as all three isomers of C6H4[CH2OCH2C(pz)3]2, will form building blocks for the preparation of coordination polymers that have unusual 2-D or 3-D supramolecular structures. Metal complexes of tpm ligands may show unique reactivity or catalytic activity. The coordination polymers, especially those containing two different metals, will have interesting physical or electronic properties. In addition, several graduate students and faculty members, including coworkers from a HBCU undergraduate institution, will have the opportunity to participate in the research project.

丹尼尔湖Reger，南卡罗来纳州哥伦比亚大学化学和生物化学系，因其开发三（苯甲酰基）甲烷（tpm）配体的新金属络合物的工作而得到无机，生物无机和有机化学计划的支持。这些配体与三（苯甲酰基）硼酸酯密切相关，但制备起来要困难得多。Reger开发了tpm配体的新合成途径，如HC（pz）3、HC（3，5-Me 2 pz）3、HC（3-Phpz）3、HC（3-tBupz）3和HC（3-iPrpz）3。 连接的双官能和多官能邻苯二甲酰甲烷配体，如C6 H4 [CH 2 OCH 2C（pz）3]2的所有三种异构体，将形成用于制备具有不寻常的2-D或3-D超分子结构的配位聚合物的构建块。tpm配体的金属配合物可显示独特的反应性或催化活性。配位聚合物，特别是含有两种不同金属的配位聚合物，将具有有趣的物理或电子性质。此外，一些研究生和教职员工，包括来自HBCU本科院校的同事，将有机会参与该研究项目。
