5,10,15,20-Tetra-2-furylporphyrin
Mol-ecules of the title macrocycle, C(36)H(22)N(4)O(4), are located on an inversion center. The porphyrin ring shows a wave-like conformation with adjacent pyrrole rings tilted above the porphyrin plane and the inter-porphyrin distance is 3.584 (3) Å. The dihedral angles between the meso-furyl groups and the porphyrin plane are 38.87 (7) and 48.29 (7)°; these are much smaller than those observe...
متن کامل2,3,4,6-Tetra-O-acetyl-2-phthalimido-β-d-glucopyranoside
In the crystal structure of the title compound, C(24)H(27)NO(11), a substituted tetra-acetyl glucopyran-oside derivative, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagated in [010]. The d configuration has been attributed on the basis of the synthesis and the β anomer has been determined from the structure.
متن کاملTetra-μ3-methanolato-tetrakis[(2-formyl-6-methoxyphenolato)methanolnickel(II)]
The molecule of the title compound, [Ni(4)(CH(3)O)(4)(C(8)H(7)O(3))(4)(CH(3)OH)(4)], has S(4) symmetry. Each of the four Ni(II) atoms occupies every other corner of a cube, with the alternate corners occupied by μ(3)-methano-late bridging groups linking to three Ni(II) atoms. Each Ni(II) atom is in an O(6) octa-hedral coordination environment formed by three O atoms from three μ(3)-methano-late...

In the structure of the title compound, [Rb(4)(C(9)H(6)NO(4))(4)(H(2)O)(6)](n), the asymmetric unit comprises four rubidium cations, two of which have an RbO(7) coordination polyhedron with a monocapped distorted octa-hedral stereochemistry and two of which have a distorted RbO(6) octa-hedral coordination. The bonding about both the seven-coordinate cations is similar, comprising one monodentat...
متن کاملPoly[[tetrakis(μ-2-anilinobenzoato-κ2 O:O′)tetra-μ1,1,1-azido-tetra-μ1,1-azido-octamethanolhexanickel(II)] methanol hexasolvate]
The crystal structure of the title compound, [Ni(6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)]·6CH(3)OH, consists of a centrosymmetric hexa-nuclear [Ni(II) (6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)] mol-ecule and six methanol solvent mol-ecules. In the hexa-nuclear unit, the six octa-hedrally coordinated Ni(II) atoms are linked by four μ(1,1,1)-azide and four μ(1,1)-azide bridges, forming a f...
