Poly[mu4-sulfido-tris(thiocyanato-kappaN)tris(mu3-1,2,4-triazolato-kappa(3)N(1):N(2):N(4))tetrazinc(II)]: a three-dimensional zinc sulfide coordination polymer.

The title compound, [Zn(4)(C(2)H(2)N(3))(3)(NCS)(3)S](n), is a three-dimensional coordination polymer consisting of tetrahedral SZn(4) clusters bridged by triazole ligands. In the tetrahedral unit, three Zn atoms are connected to six bridging triazolate ligands, whereas the fourth Zn atom (site symmetry 3m) is bonded to three terminal thiocyanate anions that protrude into the void space created by the Zn-triazolate network. The network prototype is simple cubic, but a strong distortion along a body diagonal and the imposition of a polar direction by the arrangement of the molecular constituents lead to the trigonal space group R3m.

KCd2[N(CN)2]5(H2O)4: an enmeshed honeycomb grid.

The title compound, poly[potassium [diaquapenta-micro(2)-dicyanamido-dicadmium(II)] dihydrate], {K[Cd(2)(C(2)N(3))(5)(H(2)O)(2)].2H(2)O}(n), contains two-dimensional anionic sheets of {[Cd(2){N(CN)(2)}(H(2)O)(2)](-)}(n) with a modified (6,3)-net (layer group cm2m, No. 35).

Two alternating BEDT-TTF packing motifs in alpha-kappa-(BEDT-TTF)2Hg(SCN)3.

The first BEDT-TTF charge transfer salt in which alternating electron-donor layers possess alpha- and kappa-type packing motifs has been synthesized. The crystal structure and physical properties of the organic conductor alpha-kappa-(BEDT-TTF)2Hg(SCN)3 are described, including a detailed description of its optical properties. The electronic behavior is dominated by a sharp metal-to-insulator transition at T = 176 K which is due to a first-order structural phase transition.

Poly[tetraphenylphosphonium copper(I)-di-micro2-dicyanamido].

In the title compound, [(C(24)H(20)P)[Cu(C(2)N(3))(2)]](n), the copper(I) dicyanamide anion forms a distorted three-dimensional single diamondoid network. Templating tetraphenylphosphonium cations reside within the cavities of the polymeric anion.

Bis(4,4'-bipyridinium) hexacyanoplatinate(IV) bis(4,4'-bipyridine).

In the title compound, (C10H9N2)2[Pt(CN)6].2C10H8N2 or [(Hbpy)+]2[Pt(CN)6](2-).2bpy, where bpy is 4,4'-bipyridine, the Hbpy+ cations and bpy molecules form a hydrogen-bonded two-dimensional cationic approximately square grid parallel to the (110) plane.
