Three copper(II) salts with a chloride, bromide or nitrate counterions in combination with the ditopic ligand 1,3-bis(imidazol-1-ylmethyl)benzene (L) were used to study the influence of the metal to ligand molar ratio on the formation of the final product. Single-crystal X-ray analysis revealed structural diversity of the products formed, ranging from discrete species to extended 1D and 2D coordination polymers. Similar types of 1D chains were formed for all counterions.Scheme 1 1,3-Bis(imidazol-1-ylmethyl)benzene (L).

A novel distal bidentate S/S resorcinarene ligand has been synthesised and a bis-mu-chloro-bridged palladium(II) complex obtained. The solid state structure for this complex represents the first crystal structure evidence for a bispalladium-mu-chloro-bridged complex bound to thioether ligands. Furthermore, solution NMR studies revealed conformational changes in the flexible resorcinarene ligand and discreet transient chirality around the sulfur centres.

The title compound, C20H16NO3P, was synthesized by the addition of diphenyl­phosphine chloride to a tetra­hydro­furan solution of Et3N and 2-methyl-1,3-benzoxazol-4-ol at 233 K. In the mol­ecule, the almost planar (r.m.s. deviation = 0.010 Å) benzoxazole moiety is attached to the slightly distorted tetra­hedral P atom [C—P—C—C torsion angle = 132.20 (18)°]. The crystal structure does not exhibit any significant inter­molecular inter­actions.
