Crystal structure of catena-poly[ N, N, N′, N′-tetra­methyl­guanidinium [(chlorido­cadmate)-di-μ-chlorido]]

Abstract

The structure of the title salt, {(C ₅H ₁₄N ₃)[CdCl ₃]} _n , consists of infinite zigzag polyanionic ¹ _∞[CdCl _4/2Cl _1/1] ⁻ chains held together by tetra­methyl­guanidinium cations through N—H⋯Cl hydrogen bonds, leading to a layered structure parallel to (010).

Abstract

In the structure of the title salt, {(C ₅H ₁₄N ₃)[CdCl ₃]} _n , the Cd ^II atom of the complex anion is five-coordinated by one terminal and four bridging Cl atoms. The corresponding coordination polyhedron is a distorted trigonal bipyramid, with Cd—Cl distances in the range 2.4829 (4)–2.6402 (4) Å. The bipyramids are condensed into a polyanionic zigzag chain extending parallel to [101]. The tetra­methyl­guanidinium cations are situated between the polyanionic chains and are linked to them through N—H⋯Cl hydrogen bonds, forming a layered network parallel to (010).
