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.
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...
متن کاملCalcium 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...
متن کاملA triclinic polymorph of 3-nitroanilinium chloride
The asymmetric unit of the title compound, C(6)H(7)N(2)O(2) (+)·Cl(-), contains two independent ion pairs. A monoclinic form of the title compound with only one ion pair in the asymmetric unit has been reported previously [Ploug-Sørensen & Andersen (1986). Acta Cryst. C42, 1813-1815]. In the crystal of the title compound, the components are linked into layers parallel to (001) by inter-molecula...
متن کاملA triclinic polymorph of hexanedioic acid
Hexane-dioic acid (or adipic acid), C(6)H(10)O(4), crystallizes with two crystallographically independent half-mol-ecules in the asymmetric unit of the triclinic unit cell, space group P, as each mol-ecule lies across a crystallographic inversion centre. A monoclinic polymorph has been reported previously, most recently by Ranganathan, Kulkarni & Rao [J. Phys. Chem. A, (2003), 107, 6073-6081]. ...
