Crystal and Molecular Structure of (C6H5)2SnSAT, (SAT = Tridentatte Dianion from 2-(o-Hydroxyphenyl)benzothiazoline)(C6H5)2SnSAT, C25H19NOSSn (SAT = tridendate dianion of SCHIFT base form, derived from 2-(o-hydroxyphenyl)benzothiazoline), crystallizes in the space group P21/n(C2h5) with a = 9.65(1), b = 16.08(1), c = 13.83(1) Å, β = 94.95(10)° Z = 4. The crystal and molecular structure has been solved using 3150 symmetrical independent reflections and applying the heavy atom method; the position of all atoms, except the H atoms has been determined. As interatomic distances have been found: Sn—S: 2.496(1) Å, Sn—O: 2.093(2) Å, Sn—N: 2.217(3) Å, Sn—C 1 (phenyl group I): 2.120(3) Å, Sn—C 7 (phenyl group II): 2.126(3) Å, O—C: 1.324(4) Å, C 19-N (Schief base bridging group): 1.287(5) Å, C 19-C: 1.448(5) Å, N—C: 1.419(5) Å, mean C—C distances in the two phenyl groups at Sn: 1.391(6) Å. The coordination polyhedron around Sn has essentially trigonal bipyramidal structure, which however is heavily distorted; N and the two Sn-phenylgroups occupy the equatorial positions.
Notes:
(C6H5)2SnSAT, C25H19NOSSn (SAT = dreizähniges Dianion mit Schiffscher Base-Struktur, abgeleitet von 2-(o-Hydroxyphenyl)benzothiazolin), kristallisiert in der Raumgruppe P21/n (C2h5) mit a = 9,65(1), b = 16,08(1), c = 13,83(1) Å, β = 94,95(10)° und Z = 4. Die Kristall- und Molekülstruktur wurde an Hand von 3150 symmetrisch unabhängigen Reflexen nach der Schweratommethode bestimmt und die Atomlagen bis auf die der Wasserstoffatome ermittelt. Für die interatomaren Abstände im Molekül wurden gefunden: Sn—S: 2,496(1) Å, Sn—O: 2.093(2) Å, Sn—N: 2,217(3) Å, Sn—C 1 (Phenylrest I): 2,120(3) Å, Sn—C 7 (Phenylrest II): 2,126(3) Å, O—C: 1,324(4) Å, C 19-N (Brückenglied der Schiffschen Base): 1,287(5) Å, C 19-C: 1,448(5) Å, N—C: 1,419(5) Å, Mittelwert der C—C-Abstände der beiden Phenylreste an Sn: 1,391(6) Å. Das Koordinationspolyeder um das Sn-Atom hat die Grundstruktur einer trigonalen Bipyramide, die jedoch erheblich verzerrt ist; N und die beiden Phenylgruppen am Sn liegen äquatorial.
