N-(4-Methoxybenzyl)phthalimide: a triclinic polymorph
THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(4-meth-oxy-benz-yl)-isoindoline-1,3-dione], C(16)H(13)NO(3), represents a triclinic polymorph of the previously reported monoclinic form [Warzecha et al. (2006 ▶). Acta Cryst. E62, o5450-o5452]. The reaction of potassium phthalimide and 4-meth-oxy-benzyl chloride in dimethyl-formamide gave platelet-shaped crystals; these were harvested and then needle-sha...
متن کاملA triclinic polymorph of N-[4-(4-methylbenzenesulfonamido)phenylsulfonyl]acetamide
In the asymmetric unit of the title compound, C(15)H(16)N(2)O(5)S(2), there are two symmetry-independent mol-ecules which adopt similar conformations, with dihedral angles between the aromatic rings of 59.30 (8) and 61.81 (8)°, and dihedral angles between acetamide group and the benzene ring of 77.08 (10) and 78.40 (10)°. Each type of mol-ecule forms similar one-dimensional polymeric structures...
متن کاملTriclinic polymorph of 4-[4-(4-formylphenoxy)butoxy]benzaldehyde
The title compound, C18H18O4, is a triclinic polymorph of the previously reported monoclinic polymorph [Han & Zhen (2005 ▶). Acta Cryst. E61, o4358-o4359]. In the crystal of the triclinic polymorph, molecules are linked by two pairs of C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (102), and enclosing loops with graph set motifs of R2(2)(8) and R2(2)(6).
متن کاملA triclinic polymorph of (E)-2-(4-isobutylphenyl)-N′-[1-(4-nitrophenyl)ethylidene]propanohydrazide
The asymmetric unit of the triclinic polymorph of the title compound, C21H25N3O3, consists of two mol-ecules, whereas for the monoclinic polymorph Z' = 1 [Fun et al. (2009 ▶). Acta Cryst. E65, o445]. The two mol-ecules exhibit an E configuration with respect to the C=N bond. The mol-ecules are linked into dimers by N-H⋯O and C-H⋯O hydrogen bonds forming R 2 (2)(8) ring motifs. In addition, π-π ...
متن کامل4,4′-Dimethoxybenzophenone: a triclinic polymorph
The title compound, C(15)H(14)O(3), has been found to crystallize as a new triclinic polymorph. The asymmetric unit of the present structure, as in the previously reported monoclinic structure [Norment & Karle (1962 ▶). Acta Cryst. 15, 873-878], contains two independent mol-ecules, which differ slightly in the orientations of the two benzene rings. The crystal packing of the triclinic polymorph...
