[1-9-NαC]-Linusorb B3 (Cyclo-linopeptide A) dimethyl sulfoxide monosolvate.

ABSTRACT: Crystals of the dimethyl sulfoxide (DMSO) solvate of [1-9-NαC]-linusorb B3 (Cyclo-linopeptide A; CLP-A; C₅₇H₈₄N₉O₉·C₂H₆OS), a cyclic polypeptide were obtained following peptide extraction and purification from flaxseed oil. There are four intramolecular N-H⋯O hydrogen bonds. In the crystal, the mol-ecules are linked in chains along the a axis by N-H⋯O hydrogen bonds. Each DMSO O atom accepts a hydrogen bond from an NH group at the Phe⁶ location in the CLP-A mol-ecule.

cis-Dichlorido-tetra-kis-(dimethyl sulfoxide-κO)chromium(III) chloride dimethyl sulfoxide monosolvate.

Project description:The structure of the title compound, [CrCl2(C2H6OS)4]Cl·C2H6OS, consists of a Cr(III) ion coordinated by four O atoms of dimethyl sulfoxide (DMSO) ligands and two chloride ions in cis positions, forming a distorted CrCl2O4 octa-hedron. An isolated Cl(-) counter-anion and a positionally disordered DMSO mol-ecule [occupancy ratio 0.654 (4):0.346 (4)] are also present. In the structure, the complex cations inter-act with the Cl(-) counter-anions and the DMSO solvent mol-ecules via weak C-H⋯Cl and C-H⋯O inter-actions, forming a three-dimensional network.

Alternariol 9-O-methyl ether dimethyl sulfoxide monosolvate.

Project description:The title compound (systematic name3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one dimethyl sulfoxide monosolvate), C15H12O5·C2H6OS, was isolated from an unidentified endophytic fungus (belonging to class Ascomycetes) of Taxus sp. In the crystal, both the alternariol 9-O-methyl ether (AME) and the dimethyl sulfoxide (DMSO) mol-ecules exhibit crystallographic mirror symmetry. One of the hy-droxy groups makes bifurcated hydrogen bonds, viz. an intra-molecular bond with the carbonyl group and an inter-molecular bond with the carbonyl group in an inversion-related AME mol-ecule. In the crystal, the AME mol-ecules are organized into stacks parallel with the b axis by π-π inter-actions between centrosymmetrically related mol-ecules [the distance between the centroid of the central ring and the centroid of the meth-oxy-substituted benzene ring in the next mol-ecule of the stack is 3.6184 (5) Å]. Pairs of DMSO mol-ecules, linked via centrosymmetric C-H⋯O contacts, are inserted into the voids created by the AME mol-ecules, making O-H⋯O and C-H⋯O contacts with the hosts.

cis-Bis(2,2'-bipyridine-κN,N')bis-(dimethyl sulfoxide-κO)zinc bis-(tetra-phenyl-borate) dimethyl sulfoxide monosolvate.

Project description:In the mononuclear title complex, [Zn(C(10)H(8)N(2))(2)(C(2)H(6)OS)(2)](C(24)H(20)B)(2)·C(2)H(6)OS, the Zn(II) ion is coordinated by four N atoms of two bidentate 2,2'-bipyridine mol-ecules and by the O atoms of two cis-disposed dimethyl sulfoxide mol-ecules in a distorted octa-hedral geometry. The S atom and the methyl groups of one of the coordinated dimethyl sulfoxide mol-ecules are disordered in a 0.509 (2):0.491 (2) ratio. The crystal packing is stabilized by C-H⋯O hydrogen bonds between the dimethyl sulfoxide solvent mol-ecules and tetra-phenyl-borate anions.

2-Amino-1-methyl-1H-imidazol-4(5H)-one dimethyl sulfoxide monosolvate.

Project description:In the title compound, C(4)H(7)N(3)O·C(2)H(6)OS, creatinine [2-amino-1-methyl-1H-imidazol-4(5H)one] exists in the amine form. The ring is planar (r.m.s. deviation for all non-H atoms = 0.017 Å). In the crystal, two creatinine mol-ecules form centrosymmetric hydrogen-bonded dimers linked by pairs of N-H⋯N hydrogen bonds. In addition, creatinine is linked to a dimethyl sulfoxide mol-ecule by an N-H⋯O inter-action. The packing shows layers parallel to (120).

[1,2-Bis(diphenyl-phosphan-yl)ethane-?(2)P,P']dichloridopalladium(II) dimethyl sulfoxide monosolvate.

Project description:In the title compound, [PdCl(2)(C(26)H(24)P(2))]·C(2)H(6)OS, the Pd(II) atom adopts a distorted cis-PdCl(2)P(2) square-planar coordination geometry. The five-membered chelate ring adopts an envelope conformation with a methyl-ene C atom in the flap position. The S and C atoms of the dimethyl sulfoxide (DMSO) solvent mol-ecule are disordered over two sets of sites in a 0.8976?(18):0.1024?(18) ratio. The DMSO O atom accepts three C-H?O hydrogen bonds from an adjacent complex mol-ecule.

Pyrimethaminium 2-{[4-(tri-fluoro-meth-yl)phen-yl]sulfan-yl}benzoate dimethyl sulfoxide monosolvate.

Project description:In the cation of the title solvated mol-ecular salt, C12H14ClN4 (+)·C14H8F3O2S(-)·C2H6OS [systematic name of the cation: 2,4-di-amino-5-(4-chloro-phen-yl)-6-ethyl-pyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chloro-phenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modelled for the dimethyl sulfoxide solvent mol-ecule over two set of sites in a 0.7487 (13):0.2513 (13) ratio. In the crystal, the cations are linked by inversion-generated pairs of N-H⋯N hydrogen bonds, with an R 2 (2)(8) graph-set motif. The cation donates two N-H⋯O hydrogen bonds to the anion, also generating an R 2 (2)(8) loop. These inter-actions, along with cation-solvent N-H⋯O hydrogen bonds, and cation-anion C-H⋯F, solvent-anion C-H⋯O and C-H⋯F inter-actions, result in a three-dimensional network.

4-(5,6-Dihydro-benzimidazo[1,2-c]quinazolin-6-yl)benzene-1,3-diol dimethyl sulfoxide monosolvate.

Project description:In the title solvated benzimidazole compound, C(20)H(15)N(3)O(2)·C(2)H(6)OS, both the benzimidazole fused-ring system and the complete dimethyl sulfoxide solvent mol-ecule are disordered over two sets of sites, in 0.750?(5):0.250?(5) and 0.882?(4):0.118?(4) ratios, respectively. The conformation of the pyrimidine ring is close to a half-chair for the major disorder component, whereas for the minor component it is close to a boat. The dihy-droxy-phenyl ring is almost perpendicular to the mean plane of the benzimidazole ring [dihedral angle = 87.3?(2)° for the major disorder component and 88.3?(5)° for the minor disorder component]. In the crystal, mol-ecules are linked into layers parallel to (110) by O-H?N and C-H?O hydrogen bonds. A bifurcated O-H?(O,S) bond links the benzimidazole and solvent mol-ecules.
