Yes—boron and beryllium can form a bond. In a 2014 report, chemists described a discrete, linear beryllium bis(diazaborolyl) compound containing two boron–beryllium bonds, characterized as polar covalent. The result was specifically reported as the first non-cluster Be–B bond, not as proof that the elements commonly bond outside specialized research chemistry.
What did the researchers make?
Thomas Arnold, Holger Braunschweig and co-authors reported a linear beryllium bis(diazaborolyl) compound. In this molecule, beryllium is bonded to two diazaborolyl groups, giving the structure two Be–B bonds. The Royal Society of Chemistry’s article record describes the compound and the authors’ characterization of its bonding: Beryllium bis(diazaborolyl): old neighbors finally shake hands.

How did they prepare and characterize it?
The team reacted Yamashita’s lithium diazaborolide with beryllium chloride (BeCl2). They used structural and spectroscopic analysis, along with reactivity studies, to characterize the product and assess the bonding. The paper describes the Be–B bonding as polar covalent. That means the bond involves shared electrons, but the sharing is uneven rather than purely equal.

What does “non-cluster” mean here?
“Non-cluster” identifies the context of the reported bond: it is part of a discrete linear compound, rather than a bond occurring within a cluster compound. The paper’s priority claim is narrow—the first reported non-cluster bond between boron and beryllium. It should not be broadened into a claim that no conceivable boron–beryllium interaction had ever been discussed in any setting.
When was the discovery published?
The Royal Society of Chemistry record gives 11 November 2014 as the first online publication date. The article was later assigned to the 2015 issue of Chemical Communications, volume 51, issue 4, pages 737–740. PubMed lists 14 January 2015 as the issue date; that bibliographic date is compatible with the publisher’s earlier online-first date. See the PubMed record for the issue citation. Jennifer Newton’s contemporaneous Chemistry World report appeared on 24 November 2014: Boron and beryllium finally shake hands.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why does the result matter—and what does it not show?
The finding added a specific kind of bond to the reported chemistry of neighboring elements: a characterized, polar-covalent Be–B bond in a non-cluster compound. It is a result about a prepared research molecule, not evidence that boron and beryllium commonly bond in everyday materials or that the compound has a consumer use. The RSC record provides supplementary information and crystallographic data for readers seeking the research files: the article record.
