چکیده
The asymmetric unit of the title compound {(C6H18N2)2[Sb2Br10]·H2O} n , consists of two tetra-methyl-ethylendi-ammonium cations that are located on centres of inversion, as well as one tetra-methyl-ethylendi-ammonium cation, one water mol-ecule, one distorted octahedral [SbBr6](3-)anion and one bisphenoidal [SbBr4](-) anion in general positions. The [SbBr6](3-) and [SbBr4](-) anions are linked together by two long Sb-Br bonds of 3.2709 (8) and 3.5447 (7) Å into {[Sb2Br10](4-)} n chains along [001]. One of the three tetra-methyl-ethylendi-ammonium cations is disordered and was refined using a split model (occupancy ratio 0.58:0.42). The cations and the water mol-ecule are connected to the {[Sb2Br10](4-)} n polymeric anions by weak N-H ⋯Br and O(water)-H ⋯Br hydrogen bonding.

In the title compound, [PbBr(2)(C(14)H(12)N(2))](n), the Pb(II) atom lies on a twofold rotation axis. The N-heterocycle-chelated Pb(II) atom exists in a distorted octa-hedral geometry owing to two long Pb⋯Br inter-actions [2.9562 (5) and 3.2594 (5) Å]. These result in a zigzag chain running along the c axis. The lone pair is stereochemically inactive.

In the title polymeric complex, [HgBr(2)(C(10)H(14)N(2))](n), each nicotine mol-ecule is bonded to two adjacent Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming zigzag chains along [010]. The coordination around mercury is completed by two bromido ligands resulting in a distorted tetra-hedral arrangement.
