Structurally diverse complexes were derived from three monofunctional carboxylic acids with different numbers of phenyl groups on the \u03b1-carbon, and two bifunctional carboxylic acids with a neutral donor terminus, namely methoxyacetic and diethylphosphonoacetic acids. Donor solvents are commonly used in various transformations of alkylzinc carboxylates, therefore the effect of THF as a donor solvent on the reaction outcome was also investigated. Reactions of equimolar amounts of Et<sub>2<\/sub>Zn and the selected carboxylic acid in a THF solutions gave ethylzinc carboxylates with a large variety of structures. In the cases of triphenylacetic and diphenylacetic acids, a THF solvated products of stoichiometry [EtZn(O<sub>2<\/sub>CR)(THF)] were isolated as a dimer and a 1D coordination polymer, respectively, whereas with methoxyacetic acid, a novel solvent-free hexanuclear structural motif with a butterfly-like framework was formed, ([EtZnO<sub>2<\/sub>CCH<sub>2<\/sub>OCH<sub>3<\/sub>]<sub>6<\/sub>. The corresponding reaction with diethylphosphonoacetic acid produced a rare example of a nonanuclear organozinc oxo carboxylate cluster, [(EtZn)<sub>8<\/sub>Zn(<i>\u03bc<\/i><sub>3<\/sub>-O)<sub>2<\/sub>(O<sub>2<\/sub>CCH<sub>2<\/sub>(O)P(OEt)<sub>6<\/sub>)].<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter  wp-image-2004\" alt=\"om2015_caroboxylates\" src=\"wp-content\/uploads\/2015\/10\/om2015_carboxylates-copy.png\" width=\"670\" \/><\/p>\n<p><a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.organomet.5b00557?src=recsys\" target=\"_blank\">Paper on ACS website<\/a><\/p>\n<p><a href=\"wp-content\/uploads\/2015\/11\/om2015_carboxylates.pdf\" target=\"_blank\">Full-text PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Organometallics, 2015, 34, 4959\u20134964. &nbsp; Structural Diversity of Ethylzinc Carboxylates Agnieszka Grala,a Ma\u0142gorzata Wolska-Pietkiewicz,a Anna Wojew\u00f3dzka,a Monika Dabergut,a Iwona Justyniak,b Janusz Lewi\u0144ski*ab a\u00a0Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3, 00-664 Warsaw, Poland b\u00a0Institute of Physical Chemistry, Polish Academy of Sciences, Kasprzaka 44\/52, 01-224 Warsaw, Poland DOI: 10.1021\/acs.organomet.5b00557.
