{4-Amino-N'-[(2-oxidonaphthalen-1-yl)methyl-idene]benzohydrazidato}di-methyl-tin(IV).

ABSTRACT: In the title compound, [Sn(CH3)2(C18H13N3O2)], the Sn(IV) ion is coordinated by one N and two O atoms from the tridentate 4-amino-N'-[(2-oxidonaphthalen-1-yl)methyl-idene]benzohydrazidate(2-) ligand and two C atoms from methyl ligands in a distorted trigonal-bipyramidal geometry. The dihedral angle between the naphthalene ring system and the benzene ring is 19.2?(2)°. In the crystal, weak N-H?O hydrogen bonds link the mol-ecules into zigzag chains along [010].

{4-Hy-droxy-N'-[(2-oxido-1-naphthyl-?O)methyl-idene]benzohydrazidato-?N',O}dimethyl-tin(IV).

Project description:Two independent but very similar mol-ecules comprise the asymmetric unit of the title compound, [Sn(CH(3))(2)(C(18)H(12)N(2)O(3))]. Each Sn atom is coordinated by two methyl groups and two O atoms and an N atom from the dinegative tridentate ligand. The resultant C(2)NO(2) donor set defines a coordination geometry inter-mediate between square-pyramidal and trigonal-pyramidal, with a small tendency towards the former. Zigzag chains running along the a axis mediated by O-H?N hydrogen bonding characterize the crystal packing. These are connected into layers in the ab plane by a combination of C-H?N and ?-? [centroid-centroid distances = 3.658?(2) and 3.6740?(18)?Å] inter-actions. The layers are connected along the c axis via C-H?O inter-actions.

Crystal structures of di-aquadi-μ-hydroxido-tris-[tri-methyl-tin(IV)] diformatotri-methyl-stannate(IV) and di-μ-hydroxido-tris-[tri-methyl-tin(IV)] chloride monohydrate.

Project description:The title compounds, [Sn3(CH3)9(OH)2(H2O)2][Sn(CH3)3(CHO2)2] (1) and [Sn3(CH3)9(OH)2]Cl·H2O (2), are partially condensed products of hydrolysed tri-methyl-tin chloride. In the structures of 1 and 2, short cationic tris-tannatoxanes (C9H29O2Sn3) are bridged by a diformatotri-methyl-tin anion or a chloride anion, respectively. Hydrogen bridges are present and supposedly stabilize these structures against further polymerization to the known polymeric tri-methyl-tin hydroxide. Especially noteworthy is that the formate present in this structure was formed from atmospheric CO2.

The binuclear mol-ecule of (I) is located on a general position, while the mononuclear mol-ecule of (II) is situated on a twofold rotation axis. Both ZrIV atoms in (I) are ligated by one cyclo-penta-dienyl (CP) ring and four Br ligands (two bridging, two terminal), while in (II) the ZrIV atom is ligated by two CP rings and two terminal Br ligands. The crystal structures of both (I) and (II) comprise of strands of π-π- and N-π-bonded mol-ecules, which in turn are linked by C-H⋯Br inter-actions.

Di-n-but-yl{1-[1-(2-hydroxy-phen-yl)ethyl-idene]-5-[1-(2-oxidophen-yl)ethyl-idene]thio-carbazonato-?O,N,S}tin(IV).

Project description:The 'symmetrical' 1,5-bis-[1-(2-hydroxy-phen-yl)ethyl-idene]thio-carbazone Schiff base condenses with dibutyl-tin oxide to form the title complex, [Sn(C(4)H(9))(2)(C(17)H(16)N(4)O(2)S)], in which the deprotonated ligand O,N,S-chelates to the Sn atom of two crystallographically independent mol-ecules. The ligand bears a formal negative charge on the S and one O atom; the other O atom retains its H atom. The Sn atoms are five-coordinated in a cis-C(2)NOSSn trigonal-bipyramidal environment, and the apical sites are occupied by the O and S atoms. In both mol-ecules, the hydr-oxy group is hydrogen bonded to a double-bonded N atom, generating a six-membered ring. The amino group is a donor to the coordinated O atom of an adjacent mol-ecule, the hydrogen-bonding inter-action giving rise to a helical chain running along the b axis. In one of the independent mol-ecules, the atoms of one of the n-butyl groups are disordered over two sets of sites with equal occupancy. In the other independent mol-ecule, the atoms of both n-butyl groups are disordered over two sets of sites with equal occupancy and, in addition, the Sn and S atoms were also refined as disordered over two sets of sites with equal occupancy.
