The products have been formulated as M2(\u03bc-OH)2(\u03bc-C4O4)2(H2O)4\u00b72H2O, where M = Cr (1) and Mo (2), based on combustion elemental analysis, infrared spectroscopy, magic angle spinning (MAS) solid-state carbon-13 nuclear magnetic resonance (NMR), and single-crystal X-ray diffraction. The edge-shared bioctahedral structures involve doubly bridging hydroxide ligands and \u03bc-squarate ligands. The chromium compound lacks a direct metal\u2013metal-bonding interaction, while in contrast the molybdenum compound contains a Mo\u2013Mo bond [2.491(2) \u00c5]. The nature of the Mo\u2013Mo-bonding interaction is compared with that of other similar d3\u2013d3 dimers.<\/jats:p>","DOI":"10.1021\/acsomega.0c00083","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T08:53:22Z","timestamp":1582880002000},"page":"4668-4672","source":"Crossref","is-referenced-by-count":2,"title":["Hydrothermal Synthesis and Structure of a Dinuclear\nMolybdenum(III) Hydroxy Squarate with a Mo\u2013Mo Bond"],"prefix":"10.1021","volume":"5","author":[{"given":"Greg D.","family":"Barber","sequence":"first","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["Altoona, Pennsylvania, United States, 16601"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christy","family":"George","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["University Park, Pennsylvania, United States, 16801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn","family":"Hogg","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["Altoona, Pennsylvania, United States, 16601"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shae T.","family":"Johnstone","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["Altoona, Pennsylvania, United States, 16601"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5607-5517","authenticated-orcid":true,"given":"Carlos N.","family":"Pacheco","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["University Park, Pennsylvania, United States, 16801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hemant P.","family":"Yennawar","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["University Park, Pennsylvania, United States, 16801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3872-0313","authenticated-orcid":true,"given":"William G.","family":"Van Der Sluys","sequence":"additional","affiliation":[{"name":"The Pennsylvania State University , , , ,","place":["Altoona, Pennsylvania, United States, 16601"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,2,28]]},"reference":[{"key":"2026090212433552300_cit1","doi-asserted-by":"publisher","first-page":"6834","DOI":"10.1039\/c0dt01722a","article-title":"From molecules\nto materials: molecular paddle-wheel synthons of macromolecules, cage\ncompounds and metal-organic frameworks","volume":"40","author":"Ko\u0308berl","year":"2011","journal-title":"Dalton\nTrans."},{"key":"2026090212433552300_cit2","doi-asserted-by":"crossref","DOI":"10.1007\/b136230","volume-title":"Multiple Bonds Between\nMetal Atoms","author":"Cotton","year":"2005","edition":"3"},{"key":"2026090212433552300_cit3","doi-asserted-by":"publisher","first-page":"219","DOI":"10.1021\/ic701937c","article-title":"Very large\ndifference in electronic communication of dimetal species with heterobiphenylene\nand hetroanthracene","volume":"47","author":"Cotton","year":"2008","journal-title":"Inorg.
