A triclinic polymorph of dicadmium divanadate(V)
The title compound, Cd2V2O7, was obtained under hydro-thermal conditions. Different from the known monoclinic form, the new polymorph of Cd2V2O7 has triclinic symmetry and is isotypic with Ca2V2O7. The building units of the crystal structure are two Cd(2+) cations, with coordination numbers of six and seven, and two V atoms with a tetra-hedral and a significantly distorted trigonal-pyramidal co...
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 کاملTriclinic 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 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...
