Synthesis and Crystal Structure of Drum Organooxotin Clusters from Heteroaromatic Carboxylic Acid [PhCH 2 Sn(O)(O 2 CC 5 H 4 N)] 6 and [PhCH 2 Sn (O) (O 2 CC 4 H 3 O)] 6

Two novel drum organooxotin dusters [PhCH 2 Sn(O)‐ (O2CC 5 H 4 N)] 6 (1) and [PhCH 2 Sn(O)(O 2 CC 4 H 3 O)] 6 (2) were synthesized by the reaction of [(PhCH 2 ) 3 Sn] 2 O with 2‐pyridinecarboxylic acid and 2‐furancarboxylic add in 1:2 molar ratio. Their structures were determined by X‐ray single crystal diffraction analysis. The crystal 1 belongs to monoclinic with space group P 2(1)/ c , a = 1.2194(6) nm, b = 1.2378(2) nm, c = 2.6084(4) mn, β = 94.148(3)°, Z = 2, V= 3.9270(11) mn 3 , D c = 1.765 kg/m 3 , μ = 1.951 mm‐ 1 , F (000)=2040, R = 0.0516, w R = 0.0989. The crystal 2 belongs to orthorhombic with space group Pccn , a = 2.0300(6) nm, b = 2.2670(6) nm, c = 1.6088(5) nm, β = 90°, Z = 4, V =7.404(4) nm 3 , D c = 1.813 g/cm 3 , μ = 2.070 mm −1 , F (000) = 3936, R = 0.0459, wR = 0.0884. Their structures show a distorted octahedral configuration with six‐coordination for the central tin atom.
