of bis-monodentate coordination models (the unusual cis bonding versus a trans linkage) to bridge the metal atoms of inorganic tubes in the formation of large-channel zincophosphite frameworks, resulting in structural and functional diversities. The thiophene-based compound also displayed higher thermal stability and removal ability for the softer Hg2+ cations from water solutions than the performance

hydrophobic ionicliquid 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BdMIM][BF4]) with water as a cosolvent, while 2 has been synthesized from identical conditions in the absence of the [BdMIM][BF4]. We also report the microwave assisted hydro-ionothermal synthesis of the known polymorph of 2, Co(H2O)2(HO3PCH2NH2CH2PO3H)2, (6), synthesized in two hours providing high quality crystals in good yield

Zinc diethyldithiocarbamate, zinc diethyldithiocarbamate-phosphate and zinc phosphate have been synthesized. They have been characterized using DTA-TG, IR spectra and X-ray. The dithiocarbamate and phosphate contents have been determined spectrophotometrically and volumetrically, respectively. Fungicidal activity of the compounds has been tested by well diffusion method using fungi Fusarium sp.

possesses a two-dimensional layered structure, and III has a three-dimensional structure closely related to the ABW zeolitic architecture. All the compounds consist of vertex linking of ZnO(4), PO(4), and HPO(4) tetrahedral units. The fundamental building unit, single four-membered ring (S4R), is present in all the cases, and the observed differences in their structures result from variations in the connectivity
Hydrothermal reversible interconversion of two zincophosphates with three-dimensional open frameworks containing diprotonated 1,4-diazacycloheptane molecules
into the 3D interrupted open framework. The 3D intersecting channel system is filled with diprotonated amine molecules. It has been observed that I forms via hydrothermaltransformation of a known ZnPO hydrate, (C5H14N2)[Zn2(HPO4)3]·H2O (II), with a closely related 3Dopen-framework structure, involving dehydration and reconstruction of Zn–O–P linkages. Interestingly, this transformation is completely
在温和的水热条件下(160°C)和1,4-二氮杂环庚烷的存在下合成了一种新的磷酸锌(ZnPO)(C 5 H 14 N 2)[Zn 2(HPO 4)3 ](I)。通过单晶X射线晶体学确定的晶体结构。角共享的ZnO 4和HPO 4四面体被安排在基于2D,三连接的4.8 2网的层中,并通过四面体HPO 4支柱链接在一起,形成3D中断的开放框架。3D相交通道系统充满了双质子化的胺分子。据观察,I通过水热转化形成已知的ZnPO水合物(C 5 H 14 N 2)[Zn 2(HPO 4)3 ]·H 2 O(II),并具有密切相关的3D开放框架结构,涉及脱水和重建Zn–O–P链接。有趣的是,这种转变在100至160°C的水热条件下是完全可逆的,其中II和I分别在低温和高温下稳定。同样,I和II可以通过固-气反应相互转化。我的水晶数据:正交晶体,空间群Pca 2 1 Pca21 ,Z = 16Z = 16
