Complexation of (N, N-diethylthiocarbamoylmethyl) diphenylphosphine sulfide with silver nitrate. The structure of the [Ag{Ph2P(S)CH2C(S)NEt2}2]NO3 complex
摘要:
(N,Diethylthiocarbamoylmethyl)diphenylphosphine sulfide, Ph2P(S)CH2C(S)NEt2, forms a distorted tetragonal bisligand complex [AgL2]NO3 with Ag+. The stability constant of the complex in acetonitrile was estimated by spectrophotometry (logK=3.7).

The crystalline complex [Ag(L1)NO3]2 (A) was isolated by the interaction of (N,N-diethylcaibamoylmethyl)diphenylphosphine sulfide Ph2P(S)CH2C(O)NEt2 (L1) with AgNO3 in different solvents at the ratios of metal:ligand = 1∶1 and 1∶2. According to the X-ray data, complexA is a center-symmetric dimer with bridge sulfur atoms. The cations of the metal are in a tetrahedral environment formed by two S atoms
结晶络合物[Ag(L1) ]2 (A)是通过(N,N-二乙基caibamoylmethyl)二苯基硫化膦Ph2P(S)CH2C(O)NEt2 (L1)与Ag 在不同溶剂中以金属:配体 = 1∶1 和 1∶2。根据X射线数据,complexA是一个中心对称的带有桥硫原子的二聚体。金属的阳离子处于由两个 S 原子和 CO 和 NO3 基团的 O 原子形成的四面体环境中。用红外光谱研究了L1与Ag 在溶液中的相互作用,并讨论了所形成配合物的结构。

Photothermographic materials are designed with increased photospeed by chemical sensitizing the photosensitive silver halide grains with a combination of compounds. A first chemical sensitizer is a specific gold(III)-containing compound and a second chemical sensitizer is a sulfur-containing compound that is a diphenylphosphine sulfide. The molar ratio of the gold (III)-containing compound to the sulfur-containing compound is at least 1:1.
