| Abstract: | A series of new nickel complexes, namely Tp*Ni(sub)]·EtOH (1), Tp*Ni(ad)]·EtOH (2), Tp*Ni(seb)(H2O)] (3), and Tp*Ni(μ–suc)NiTp*(MeOH)2] (4) (Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, H2sub = suberic acid, H2ad = adipic acid, H2seb = sebacic acid, H2suc = succinic acid), were synthesized in mixed solvents at room temperature. The complexes were characterized by physico-chemical and spectroscopic methods. In addition, X-ray crystal structure analysis indicates that the four complexes share a common scorpionate (Tp*) Ni core with different aliphatic dicarboxylic acid ligands, and the nickel atom is in a distorted octahedral environment with the N3O3 donor set. Surface voltage spectroscopy indicates that these complexes exhibit surface photovoltage responses in the range of 300–800 nm, which can be assigned to LMCT and d → d * electronic transitions. In addition, quantum chemistry calculations on the complexes were performed and are discussed. |
