| description | In this work, we studied lead(II) and cobalt(II) complexation of derivatives [2-B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>2</sub>O(CH<sub>2</sub>)<sub>2</sub>N<sub>3</sub>]<sup>2−</sup> and [2-B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>5</sub>N<sub>3</sub>]<sup>2−</sup> of the <i>closo</i>-decaborate anion containing pendant azido groups in the presence of 1,10-phenanthroline and 2,2′-bipyridyl. Mononuclear [PbL<sub>2</sub>{An}] and binuclear [Pb<sub>2</sub>L<sub>4</sub>(NO<sub>3</sub>)<sub>2</sub>{An}] lead complexes (where {An} is the N<sub>3</sub>-substituted boron cluster) were isolated and studied by IR spectroscopy and elemental analysis. The mononuclear lead(II) complex [Pb(phen)<sub>2</sub>[B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>2</sub>O(CH<sub>2</sub>)<sub>2</sub>N<sub>3</sub>] and the binuclear lead(II) complex [Pb<sub>2</sub>(phen)<sub>4</sub>(NO<sub>3</sub>)<sub>2</sub>[B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>5</sub>)N<sub>3</sub>] were determined by single-crystal X-ray diffraction. In complex [Pb<sub>2</sub>(phen)<sub>4</sub>(NO<sub>3</sub>)<sub>2</sub>[B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>5</sub>)N<sub>3</sub>], the boron cluster is coordinated by the metal atom only via the 3c2e MHB bonds. In complex [Pb(phen)<sub>2</sub>[B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>2</sub>O(CH<sub>2</sub>)<sub>2</sub>N<sub>3</sub>], the coordination environment of the metal includes BH groups of the boron cluster and the oxygen atom of the exo-polyhedral substituent. When the reaction was performed in a CH<sub>3</sub>CN/water mixture, the binuclear lead(II) complex [(Pb(bipy)NO<sub>3</sub>)(Pb(bipy)<sub>2</sub>NO<sub>3</sub>)(B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>2</sub>O(CH<sub>2</sub>)<sub>2</sub>N<sub>3</sub>)]·CH<sub>3</sub>CN·H<sub>2</sub>O was isolated, where the boron cluster acts as a bridging ligand between lead atoms coordinated by the boron cage via the O atoms of the substituent and/or the BH groups. In the course of cobalt(II) complexation, the starting compound (Ph<sub>4</sub>P)<sub>2</sub>[B<sub>10</sub>H<sub>9</sub>O(CH<sub>2</sub>)<sub>5</sub>N<sub>3</sub>] was isolated and its structure was also determined by X-ray diffraction. Although a number of lead(II) complexes with coordinated N<sub>3</sub> are known from the literature, no complexes with the boron cluster coordinated by the pendant N<sub>3</sub> group involved in the metal coordination have been isolated. |
