Redetermination of the crystal structure of di­methyl­bis­[2,4-penta­nedionato(1−)-κ(2) O (2),O (4)]tin(IV)

The redetermination of the title compound, [Sn(CH(3))(2)(C(5)H(7)O(2))(2)] or SnMe(2)(acac)(2), from CCD data recorded at 100 K basically confirms the previous study based on integrated film data recorded at room temperature [Miller & Schlemper (1972 ▸). Inorg. Chem. 12, 677–681], but reveals a...

description The redetermination of the title compound, [Sn(CH(3))(2)(C(5)H(7)O(2))(2)] or SnMe(2)(acac)(2), from CCD data recorded at 100 K basically confirms the previous study based on integrated film data recorded at room temperature [Miller & Schlemper (1972 ▸). Inorg. Chem. 12, 677–681], but reveals a remarkable shrinkage of the a axis [7.12 (1) > 6.7694 (4) Å]. The mol­ecule belongs to point group C(i) with the Sn(IV) atom on a centre of inversion. The Sn(IV) atom shows a slightly distorted octa­hedral coordination sphere with the methyl groups in trans positions and a Sn—C bond length of 2.115 (2) Å which may serve as a standard value for an Sn—CH(3) bond of an octa­hedrally coordinated Sn(IV) atom. The Sn—O bonds involving the two carbonyl groups of the acetyl­acetonate ligand are of equal length [2.180 (1) and 2.183 (1) Å], as are the C=O [1.273 (1) and 1.274 (1) Å] and C—C bond lengths [1.393 (2) and 1.400 (2) Å]. The acetyl­acetonate ligand deviates considerably from planarity, with a dihedral angle of 5.57 (9)° between the least-squares planes of the two acetone moieties. The four O atoms of the two symmetry-related acetyl­acetonate ligands are arranged in a nearly quadratic rectangle. Weak C—H⋯O inter­actions consolidate the crystal packing.
