A triclinic polymorph of benzanilide: disordered molecules form hydrogen-bonded chains.

In the P-1 polymorph of benzanilide or N-phenylbenzamide, C(13)H(11)NO, the molecules are linked into simple C(4) chains by N-H...O hydrogen bonds. The molecules exhibit orientational disorder, but the donor and acceptor in a given hydrogen bond may occur, independently, in either the major or the minor orientation, such that all four possible N-H.O combinations have very similar geometries. Th...

A triclinic polymorph of 4-cyano­pyridinium hydrogen chloranilate

THE ASYMMETRIC UNIT OF THE TRICLINIC POLYMORPH OF THE TITLE COMPOUND (SYSTEMATIC NAME: 4-cyano-pyridinium 2,5-dichloro-4-hy-droxy-3,6-dioxocyclo-hexa-1,4-dien-1-olate), C(6)H(5)N(2) (+)·C(6)HCl(2)O(4) (-), consists of two crystallographically independent cation-anion units, in each of which the cation and the anion are linked by an N-H⋯O hydrogen bond. In the units, the dihedral angles between ...

4,4′-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...

Calcium acamprosate: a triclinic polymorph

The title compound, poly[bis-(μ(3)-4-acetamido-propane-sulfon-ato)-calcium], [Ca(C(5)H(10)NO(4)S)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Toffoli et al. (1988 ▶). Acta Cryst. C44, 1493-1494]. The triclinic modification was found to have an all-trans configuration of the acetamido-propane chain, in contrast with the monoclinic polymorph which shows an an...

Triclinic polymorph of dibenzotetra­thia­fulvalene

Crystals of the title compound (DBTTF), C(14)H(8)S(4), feature a triclinic polymorph different from two known monoclinic polymorphs. In this form, there are two independent centrosymmetric half-mol-ecules in the asymmetric unit. Although the mol-ecular orientations are relatively similar to one of monoclinic polymorphs, the packing motif is different.
