Supramolecular aggregation sustained by secondary Sn⋯S interactions (black dashed lines) leading to (a) dimeric aggregates in (PhCH2)2Sn(S2CNEt2)2, (b) four-molecule aggregates in Me2Sn(S2CN(Et)CH2C6H4N-4)2 and (c) linear supramolecular chain in {Me2SnS2CN(CH2Ph)CH2(1,3-C6H3)CH2(PhCH2)NCS2SnMe2}2. |
