The synthesis and structural characterization of the bridging ligand, 1-methyl benzimidazole diphenylphosphine (MBDP) and its coordination with Au(I) and Ag(I) metal ions is reported. Two ligands coordinate to the metal ions in head to tail fashion forming a metallacycle coordination consisting of strong M-M bonding interaction with Au[sbnd]Au?=?2.808 and Ag[sbnd]Ag?=?3.017??. Linear coordination is observed for the gold, while the silver shows distorted tetrahedral arrangement. X-ray crystal data of [(MBDP)2Au2](CH3CN)(BF4)2 (2) crystallizes in the monoclinic system with the space group of P21/n with cell constants of a?=?8.9993 (8) ?, b?=?19.6166 (18) ?, c?=?13.4484 (12) ?, β?=?100.966 (2)°, R?=?0.026, and Rw?=?0.064. The structure of [(MBDP)2(CH3CN)4Ag2](BF4)2, (3) crystallizes in the P (?)1 space group and the unit cell is a?=?10.5423 (10) ?, b?=?10.7638 (10) ?, c?=?12.3530 (12) ?; α?=?88.592 (3)°, β?=?73.097 (3)°, γ?=?84.422 (3)°, V?=?1334.8 (2) ?3 with Z?=?1, R?=?0.034 and Rw?=?0.093. The coordinating ligand as well as both dinuclear compounds reported here are luminescent in the near UV region. As supported by the DFT theoretical work, the emission is suggested to be primarily ligand based π- π* transition.

Tris(thiazol-2-yl)phosphine, 2,has been prepared by the reaction of corresponding heteroaryl organolithium reagent and PCl3.Attempts to prepare other heteroaryl-substituted phosphines, such as tris(benzothiazol-2-yl)-(3) and tris(1-methylimidazol-2-yl)phosphines (6), using this procedure, were unsuccessful.Heteroaryltrimethylsilanes, readily accessible from the reaction between a heteroaryl organometallic reagent and chlorotrimethylsilane (CH3SiCl), afford the desired heteroaryl-substituted phosphines when treated with PCl3.The heteroaryl-silicon bonds of this silanes also undergo facile electrophilic cleavage by (C6H5)PCl2 and (C6H5)2 PCl and yield the unsymmetrically substituted phosphines.The phosphines obtained in this work react readity with (1,5-cyclooctadiene)dimethylplatinum(II) and generate cis-dimethylbis(phosphine)platinum(II) complexes in which the potentially multidenate ligands are exclusively monodentate.The coordinated phosphines are bound to platinum through the phosphorus atom of the ligand.
