In recent years, hydrothermal synthesis and structural characterization of open-framework metal phosphates templated with organic diamines have attracted the attention of scientists because they represent the interaction between organic and inorganic chemistry and can be applied in lots of branches of chemistry with their different characteristic properties. In this study, a novel open-framework polyoxometal phosphate compound (4,4'-bpyH2)2(4,4'-bpyH)[PCoW11O39].H2O was synthesized with hydrothermal method as red crystals. The compound crystallizes in the space group P2(1)/n of the monoclinic system with four formula units in a cell. The crystal is a Keggin polyoxometalate structure and contains free 4,4'-bipyridine groups and water molecule between the clusters. In addition to this novel compound, three known compounds were synthesized. Co(4,4'-bpy)2(VO2)2(HPO4)2 red crystals were synthesized hydrothermally and the compound crystallizes in the space group C2/c of the monoclinic system with four formula units in a cell. The crystal consists of [(VO2)(HPO4)]∞ helical chains and [Co(4,4'-bpy)2]2+ frameworks. Also, NaCo3(PO4)(HPO4)2 pink crystals were obtained with using hydrothermal synthesis. The compound crystallizes in the space group C2/c of the monoclinic system with four formula units in a cell. In the structure, CoO6 chains connect to the PO4 and HPO4 groups. Lastly, (enH2)3[CoW4P4O28] blue crystals were synthesized with hydrothermal method and crystallizes in the space group I4(1)/a of the tetragonal system with four formula units in a cell. The crystal consists of a [Co3W4P4O28]6- anion and three free ethylenediaminium (N2H10C2)2+ cations.

By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
