These species were prepared by using cryptand\u2010222 to solubilize the pseudohalide salts in organic solvents. The UV\/Vis spectra of these zinc metalloporphyrins are solvent\u2010dependent and exhibit large redshifted Soret bands compared with those of the [Zn(Porph)L] derivatives in which Porph is a <jats:italic>meso<\/jats:italic>\u2010porphyrinato ligand and L is a monodentate neutral axial ligand. The room\u2010temperature fluorescence spectra of the zinc complexes <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> indicate that the Q bands are not very affected by the nature of the axial ligands, and their positions are very close to those of previously reported (<jats:italic>meso<\/jats:italic>\u2010porphyrinato)zinc complexes. The quantum yields of the S<jats:sub>1<\/jats:sub>\u2009\u2192\u2009S<jats:sub>o<\/jats:sub> fluorescence of <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> range between 2.8 and 5.5\u2009%, and their fluorescence lifetimes are the same (1.7 ns). Cyclic voltammetry investigations on <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> show that the characteristic potentials for the reduction and the two first oxidations of the porphyrin ring are not very affected by the nature of the axial ligand. A third irreversible oxidation of the porphyrin ring is observed. Additional anodic irreversible waves are observed for the thiocyanato\u2010<jats:italic>N<\/jats:italic> (<jats:bold>3<\/jats:bold>) and cyanido (<jats:bold>4<\/jats:bold>) species. The solid\u2010state molecular structures of <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> are the first examples of zinc porphyrin complexes with anionic ligands. The average equatorial zinc\u2013pyrrole N atom (Zn\u2013N<jats:sub>p<\/jats:sub>) distances for <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> range between 2.083(1) and 2.117(2) \u00c5 and are much longer than those of the related pentacoordinate zinc porphyrin complexes with monodentate neutral ligands. As a consequence, the displacement of the Zn<jats:sup>2+<\/jats:sup> cation from the mean 24\u2010atom plan of the porphyrin core is significant (ca. 0.5 \u00c5), and the porphyrin core is very distorted. The crystal structures of <jats:bold>1<\/jats:bold>\u2013<jats:bold>4<\/jats:bold> are stabilized by weak intermolecular \u03c0 interactions, C\u2013H<jats:bold>\u00b7\u00b7\u00b7<\/jats:bold>Cg (Cg are the centroids of some six\u2010membered phenyl rings and five\u2010membered pyrrole rings). The molecular structure of <jats:bold>1<\/jats:bold> is further stabilized by weak intermolecular C\u2013H<jats:bold>\u00b7\u00b7\u00b7<\/jats:bold>N hydrogen bonds between one carbon atom of cryptand\u2010222 and the terminal nitrogen atom of the azido ligand.<\/jats:p>","DOI":"10.1002\/ejic.201403214","type":"journal-article","created":{"date-parts":[[2015,5,1]],"date-time":"2015-05-01T10:26:50Z","timestamp":1430476010000},"page":"2596-2610","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Insights on the UV\/Vis, Fluorescence, and Cyclic Voltammetry Properties and the Molecular Structures of Zn<sup>II<\/sup> Tetraphenylporphyrin Complexes with Pseudohalide Axial Azido, Cyanato\u2010<i>N<\/i>, Thiocyanato\u2010<i>N,<\/i> and Cyanido Ligands"],"prefix":"10.1002","volume":"2015","author":[{"given":"Zouhour","family":"Denden","sequence":"first","affiliation":[]},{"given":"Khaireddine","family":"Ezzayani","sequence":"additional","affiliation":[]},{"given":"Eric","family":"Saint\u2010Aman","sequence":"additional","affiliation":[]},{"given":"Fr\u00e9d\u00e9rique","family":"Loiseau","sequence":"additional","affiliation":[]},{"given":"Shabir","family":"Najmudin","sequence":"additional","affiliation":[]},{"given":"Cecilia","family":"Bonif\u00e1cio","sequence":"additional","affiliation":[]},{"given":"Jean\u2010Claude","family":"Daran","sequence":"additional","affiliation":[]},{"given":"Habib","family":"Nasri","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2015,5]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar9001697"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2012.04.041"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tiv.2005.06.015"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.orgel.2013.01.033"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-08-092392-5.50008-0"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja001031x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00484a027"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja030221f"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00074a013"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja01153a085"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja01136a003"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-0728(02)01056-2"},{"key":"e_1_2_6_13_2","first-page":"10","volume":"24","author":"Kim D.","year":"2003","journal-title":"Bull.
