Reported here are the single‐crystal X‐ray structure analyses of bis‐μ‐methanol‐κ 4 O : O ‐bis{[hydrotris(3‐phenyl‐2‐sulfanylidene‐2,3‐dihydro‐1 H ‐1,3‐imidazol‐1‐yl)borato‐κ 3 H , S , S ′](methanol‐κ O )sodium(I)}, [Na 2 (C 27 H 22 BN 6 S 3 ) 2 (CH 4 O) 4 ] (NaTm Ph ), bis‐μ‐methanol‐κ 4 O : O ‐bis{[hydrotris(3‐isopropyl‐2‐sulfanylidene‐2,3‐dihydro‐1 H ‐1,3‐imidazol‐1‐yl)borato‐κ 3 H , S , S ′](methanol‐κ O )sodium(I)}–diethyl ether–methanol (1/0.3333/0.0833), [Na 2 (C 18 H 28 BN 6 S 3 ) 2 (CH 4 O) 4 ]·0.3333C 4 H 10 O·0.0833CH 3 OH (NaTm iPr ), and a novel anhydrous form of sodium hydrotris(methylthioimidazolyl)borate, poly[[μ‐hydrotris(3‐methyl‐2‐sulfanylidene‐2,3‐dihydro‐1 H ‐1,3‐imidazol‐1‐yl)borato]sodium(I)], [Na(C 12 H 16 BN 6 S 3 )] ([NaTm Me ] n ). NaTm iPr and NaTm Ph have similar dimeric molecular structures with κ 3 H , S , S ′‐bonding, but they differ in that NaTm Ph is crystallographically centrosymmetric ( Z ′ = 0.5) while NaTm iPr contains one crystallographically centrosymmetric dimer and one dimer positioned on a general position ( Z ′ = 1.5). [NaTm Me ] n is a one‐dimensional coordination polymer that extends along the a direction and which contains a hitherto unseen side‐on η 2 ‐C=S‐to‐Na bond type. An overview of the structural preferences of alkali metal soft scorpionate complexes is presented. This analysis suggests that these thione‐based ligands will continue to be a rich source of interesting alkali metal motifs worthy of isolation and characterization.
