Bonvalotidine A acetone solvate from Delphinium bonvalotii Franch.

ABSTRACT:

The title compound (systematic name

5,6?-dihy-droxy-1?,14?,16?-trimeth-oxy-4-methyl-7?,8-methyl-enedi-oxy-20-ethyl-aconitan-6-yl acetate acetone monosolvate), C(27)H(41)NO(8)·C(3)H(6)O, was isolated from Delphinium bonvalotii Franch, and is a typical C(19)-diterpenoid alkaloid. The mol-ecule has a lycoctonine carbon skeleton with four six-membered rings and three five-membered rings. Three six-membered rings adopt the chair conformations while the fourth adopts a boat conformation, while the five-membered rings have the envelope conformations. The solvent mol-ecule links with the organic mol-ecule via a classical O-H?O hydrogen bond. Weak C-H?O hydrogen bonding is present in the structure. An intra-molecular O-H?O hydrogen bond also occurs.

Poly[[aquadi-?(3)-malonato-hexaphenyl-ditin(IV)] acetone solvate].

Project description:The asymmetric unit of the title polymeric complex, {[Sn(2)=(C(6)H(5))(6)(C(3)H(2)O(4))(H(2)O)]·C(3)H(6)O}(n), comprises of two Sn cations, one malonate anion and a non-coordinating acetone solvent mol-ecule. Both crystallographically independent Sn cations are five-coordinated by two O and three C atoms in a distorted trigonal-bipyrimidal geometry. One of the Sn cations is bridged by the malonate units, affording polymeric chains which run along [001]. Weak intra-molecular C-H?? inter-actions stabilize the mol-ecular structure. In the crystal structure, adjacent chains are inter-connected by inter-molecular O-H?O and C-H?O hydrogen bonds into a three-dimensional supra-molecular structure. A weak inter-molecular C-H?? inter-action is also observed.

Bis(1,3-benzothia-zol-2-amine-?N)silver(I) nitrate acetone solvate.

Project description:In the title compound, [Ag(C(7)H(6)N(2)S)(2)]NO(3)·C(3)H(6)O, the Ag(I) ion is coordinated to two benzothia-zol-2-amine ligands via the thia-zole N atoms in an approximately linear arrangement. The dihedral angle between the mean planes of the two 1,3-benzothia-zole groups is 5.9?(3)°. Both amine groups on the ligands are oriented in the same direction and are engaged in N-H?O hydrogen bonding with the nitrate counter-anion, forming one-dimensional columns along the b-axis direction. Voids created by inefficient crystal packing are occupied by acetone solvent mol-ecules which are disordered over two sites with occupancies of 0.563?(11) and 0.437?(11).

10-Formyl-2,4,6,8,12-penta-nitro-2,4,6,8,10,12-hexa-azatetra-cyclo-[5.5.0.0.0]dodecane acetone solvate.

Project description:The title compound, C(7)H(7)N(11)O(11)·C(3)H(6)O, consisting of one mol-ecule of 10-formyl-2,4,6,8,12-penta-nitro-2,4,6,8,10,12-hexa-azatetra-cyclo-[5.5.0.0(5,9).0(3,11)]dodecane (penta-nitro-mono-form-yl-hexa-aza-isowurtzitane, PNMFIW) and one acetone solvent mol-ecule, is a member of the caged hexa-azaisowurtzitane family. PNMFIW has a cage structure which is constructed from one six-membered and two five-membered rings which are linked by a C-C bond, thus creating two seven-membered rings. In the PNMFIW mol-ecule, one formyl group is bonded to the N heteroatom of the six-membered cycle, and five nitro groups are appended to other five N heteroatom of the caged structure. The acetone solvent mol-ecule is arranged beside a five-membered plane of PNMFIW with an O atom and an H atom close (with respect to the sum of the van der Waals radii) to the neighbouring nitro O atom [O?O = 2.957?(3) and 2.852?(3)?Å; O? H = 2.692?(2), 2.526?(3) and 2.432?(3)?Å].

In the crystal structure, the Schiff base mol-ecules are linked into a chain along the a axis by C-H?? inter-actions. The acetone solvent mol-ecules are attached to the chain via C-H?O hydrogen bonds.
