“…The thallium(I) complex of the benzothiazole-based scorpionate (Chart 10), [Tl(Tbz)] has also been prepared [125]. Its structure is in contrast with those of Tm R and Bm R ligands in that a monomeric species is obtained.…”

Os compostos hidrotris(2-mercaptotiazolil)borato de potássio, KMt, (1), e hidrotris(2-metimazolil)borato de potássio, KTm, (2), foram preparados ao se reagir a amina tiol correspondente com KBH 4 . Foram caracterizados por métodos espectroscópicos e análise elementar. As estruturas no estado sólido de KMt.4H 2 O e do composto 2 foram determinadas por análises de difração de raios-X. A maior maciez do ânion em KMt.4H 2 O, em comparação com 2, é indicada pela ausência de interação entre ele e o cátion, que possui moléculas de água em sua esfera de coordenação. Em KMt.4H 2 O a geometria em torno do íon potássio é octaédrica distorcida e em 2, pirâmide de base quadrada distorcida. Em 2 o íon potássio está coordenado a dois átomos de enxofre dos anéis de um mesmo ânion e a três outros átomos de enxofre pertencentes a unidades KTm vizinhas. Ambos os compostos possuem uma estrutura polimérica.Potassium hydrotris(2-mercaptothiazolyl)borate, KMt, (1) and potassium hydrotris(2-methimazole), KTm, (2), were prepared by reacting the appropriate amine thiol with KBH 4 . They were characterized by spectroscopic methods and elemental analysis. Solid state structures of KMt.4H 2 O and compound 2 were determined by X-ray diffraction analyses. The softer nature of the anion in the former as compared to 2 is indicated by the lack of interaction of the anion with the cation, that has water molecules in its coordination sphere. In KMt.4H 2 O the geometry around the potassium cation is distorted octahedral and in 2, distorted square pyramidal. In 2 the potassium ion is coordinated to two sulfur atoms of one hydrotris(methimazole)borate unit and to other three sulfur atoms belonging to neighboring KTm units. Both compounds have a polymeric structure.

“…A schematic representation of the developments in scorpionate chemistry. From left to right: hydrotris(pyrazolyl)borate (Tp) (far left) [1,2]; the soft scorpionates hydrotris(methimazolyl)borate (Tm R ; R = Me, Ph, t Bu, etc)(centre left, top) [4,5] and hydrotris(mercaptobenzothiazolyl)borate (Tbz)(centre left, below) [9]; selenium and oxygen donor systems (centre right) [6,14,15]; and the poly(alkylthioalkyl)borates (right) [3,16]. The tetrakis(thioalky)borate anion (top right) was the first alternative soft donor system to be reported [3].…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Not only has there been an increase in the range of heterocycles employed (benzoimidazole-2-thione, 6 1,3,4-thiadiazole-2-thione, 7,8 benzothiazole-2-thione, 9 thiazolidine-2-thione, 9,10 1,2,4-triazole-5-thione, 11 pyridine-2-thione, 12 pyridazine-2-thione 13 ) but the range of donor atoms has also expanded, with systems containing nitrogen, 1,2,6 , sulfur, [3][4][5][6][7][8][9][10][11][12][13] selenium, 14,15 oxygen 6 and phosphorus 16 donors (Figure 1) having all been reported. The chemistry being generated using these species is diverse, but within the reports on the complexes of soft scorpionates are results which suggest that in some circumstances these ligands may be prone to decomposition.…”

“…The chemistry being generated using these species is diverse, but within the reports on the complexes of soft scorpionates are results which suggest that in some circumstances these ligands may be prone to decomposition. 4 The hydrotris(mercaptobenzothiazolyl)borate anion (Tbz, Figure 1) was first reported in 2001, 9 yet, apart from the single thallium(I) complex in the original paper, no further metal complexes were reported until 2012. 17 Given the widespread use of these soft scorpionate ligands, this lack of utilisation hints at an underlying problem.…”
