“…Hydrolyzed products (oxides, hydroxides, and oxohydroxides) for the hydrolytic reactions of organotin halides serve as precursors for reactions with various reagents, such as carboxylic, phosphonic, phosphinic, or sulfonic acids. Several novel cluster types such as ladder,11 drum,12 O ‐capped,13 cube,14 butterfly,15 triply‐ and doubly bridged ladders,16,17 have been assembled and structurally characterized, although there is still no systematic investigation of the TPA properties of organotin compounds, one that includes the results from one‐photon absorption (OPA), one‐photon excited fluorescence (OPEF), and two‐photon excited fluorescence (TPEF) spectroscopy and the crystal structure determination.…”

(E)-3-(10-ethylphenothiazine-3-yl)acrylic acid (LCOOH) was synthesized. LCOOH reacted with Ph 3 Sn(OH) and nBu 2 SnO to afford Ph 3 SnO 2 CL (1) and {[nBu 2 SnO 2 CL] 2 O} 2 (2), respectively. The structures of all the compounds were solved by single-crystal X-ray diffraction. Compounds 1 and 2 present discrete and ladder frameworks, respectively. The one-photon absorption and excited fluorescence, and two-photon excited fluorescence spectra of all the compounds were system-

“…Organooxotin clusters have been attracting considerable attention in recent years because of their novel structures,1 their suitability for the construction of supramolecular frameworks,2 and their efficient catalysis of various organic reactions 3. Several types of organooxotin cluster, such as ladder,4a O‐capped,4b cube,4c butterfly,4d drum,4e–g football cage,5 cyclic trimer,6 among others, have been prepared and their structures established by X‐ray diffraction analysis. Recently, more studies have been focused on ligand‐bridged organooxotin clusters, such as alkyl‐bridged double‐ and triple‐ladder clusters,7 an alkyl‐bridged Sn 3 O 3 cluster,8 an eighteen‐tin‐nuclear ladder cluster,9 and double O‐capped clusters 10.…”

Hydrolysis of dibenzyltin dichloride in ethanol has been found to give an unprecedented carbonate anion (CO(3) (2-))-bridged double-ladder organooxotin cluster, [(R(2)SnO)(3)(R(2)SnOH)(2)(CO(3))](2) (1, R = C(6)H(5)CH(2)), with five tin atoms in each ladder. With the aim of obtaining organooxotin clusters with large cavities suitable for host-guest chemistry, we used 1,1'-ferrocenedicarboxylic acid (H(2)L(a)) and hexanedioic acid (H(2)L(b)) to replace the carbonate anions (CO(3) (2-)), and thereby clusters [(R(2)SnO)(3)(R(2)SnOH)(2)L(a)](2) (2) and [(R(2)SnO)(3)(R(2)SnOH)(2)L(b)](2) (3) were obtained. When 1 was treated with benzoic acid (HL(c)) in different stoichiometric ratios (1:4, 1:10), ladder cluster (R(2)SnO)(3)(R(2)SnOH)(2)(L(c))(2) (4) and drum cluster [RSn(O)L(c)](6) (5) were obtained. Through the hydrolysis of Cy(2)SnCl(2) (Cy = C(6)H(11)) and (C(6)H(5)CH(2))(2)SnCl(2), two interesting ethanolate-modified clusters [Cy(2)(C(2)H(5)O)SnOSn(C(2)H(5)O)Cy(2)](2) (6) and [(R(2)SnO)(3)(R(2)SnOH)(R(2)SnOC(2)H(5))(CO(3))](2) (7) were obtained. All the tin atoms in these ladder clusters are five-coordinate surrounded by two alkyl groups and three O atoms, and have distorted trigonal-bipyramidal coordination environments with two carbon atoms and one O atom in the equatorial positions and two O atoms in the axial positions. The structures of all these compounds have been established by single-crystal X-ray diffraction analyses.
