Summary: A systematic investigation on the reactivity of hydroxy-substituted derivative of closo-dodecaborate anion [B12H11OH]2- in silver(I) and lead(II) complexation, with the presence of various organic ligands, has been conducted. Several salts and complexes of silver(I) and lead(II) with different compositions and structures have been synthesized and characterized. X-ray diffraction analysis revealed the structures of polymeric {Ag2(bipy)2[B12H11OH]}n, binuclear [Ag2(bpa)2[μ-B12H11OH]] silver(I) complexes, dimeric binuclear lead(II) complex [Pb(bipy)2[μ-B12H11OH]]2, as well as salts CsNO3•Cs2[B12H11OH] and (Hbpa)2[B12H11OH]. The coordination of the boron cluster anion by metal atoms is achieved through the formation of three-center two-electron MHB bonds with the BH groups of the polyhedron and the involvement of the oxygen atom of the substituent in metal coordination, with co-crystallization of several bond and positional isomers observed in the structures of silver(I) complexes.

Summary: This study investigated the halogen bonding between DITFBs and thiocarbonyl acceptors using single-crystal X-ray diffraction. The results showed that the lengths of contacts in the complexes were shorter than the sum of van der Waals radii and the contact angles were close to linear, confirming the existence of halogen bonding interactions. The solid-state packing of thiocarbonyl-XB complexes was greatly influenced by the size and type of the acceptor, with sulfur atoms capable of accepting multiple XB interactions.

Summary: This review summarizes data on the main types of charge-compensated nido-carborane derivatives, which have increased stability compared to organic analogs. The stability is attributed to the stabilizing electron-donor action of the boron cage. The charge-compensated derivatives are discussed based on the type of heteroatom bonded to a boron atom.

Summary: Based on the data of 1H NMR spectra, the effect of various substituents at boron atoms in different positions of the ortho-carborane cage on its CH-acidity and the electron-withdrawing effect upon substitution at the carbon atom is discussed. It is found that the introduction of chlorine atoms slightly reduces the CH-acidity, whereas the introduction of bromine and iodine atoms significantly increases the CH-acidity compared to the parent orthocarborane. The introduction of halogen atoms to the boron atoms bound to both carbon atoms leads to a significant increase in the CH-acidity, regardless of halogen electronegativity. However, in the case of polychlorinated derivatives of ortho-carborane, the total effect of the substituent covers the decrease in CH-acidity when the first halogen atoms are introduced into specific positions. The introduction of alkyl substituents reduces the CH-acidity, while the introduction of aryl substituents has the opposite effect.

Summary: In this study, a gadolinium-boron-conjugated albumin (Gd-MID-BSA) was developed for MRI-guided neutron capture therapy. The accumulation of Gd-MID-BSA in tumors was confirmed by MRI and biodistribution analysis. The concentration ratios of boron and gadolinium in tumors satisfied the requirements for boron neutron capture therapy (BNCT) and gadolinium neutron capture therapy (GdNCT). The conjugation of gadolinium and boron in the albumin molecule enhanced the therapeutic effect of BNCT and showed potential as a promising treatment for malignant tumors.

Summary: The reaction of 9-iodo-ortho-carborane with n-butylmagnesium bromide produces 9-n-butyl-ortho-carborane. Further reaction of this compound with alkali in boiling ethanol yields a new nido-carborane [5-Bu-7,8-C2B9H11](-) (I) with a n-butyl substituent. Subsequent reaction of compound I with RuCl2(PPh3)(Ph2P(CH2)(4)PPh2) leads to the formation of a ruthenium(IV) closo complex 3,3-(Ph2P(CH2)(4)PPh2)-3-H-3-Cl-9-Bu-closo-3,1,2-RuC2B9H10 (II) characterized by 2D NMR spectroscopy. Heating compound II with carbon tetrachloride results in the formation of the 17-electron complex 3,3-(Ph2P(CH2)(4)PPh2)-3-Cl-9-Bu-closo-3,1,2-RuC2B9H10, and the structure of this complex is determined using X-ray diffraction.
