AI Article Synopsis
- The title compound, ammineaquadi-mu(5)-phosphato-trizinc(II), features a structure made up of two main components: phosphate (PO(4)) and zinc (ZnO(4)) tetrahedra, which are layered and interconnected.
- Elemental analysis indicates a ratio of ammonia to water of 3:2, revealing the interaction between different molecules in the structure.
- A unique aspect of the structure is the coexistence of ammonia (NH(3)) and water (H(2)O) at the same crystallographic position, which alters hydrogen bonding patterns compared to similar structures.
Article Abstract
The structure of the title compound, ammineaquadi-mu(5)-phosphato-trizinc(II), [Zn(3)(PO(4))(2)(H(2)O)(0.8)(NH(3))(1.2)], consists of two parts: (i) PO(4) and ZnO(4) vertex-sharing tetrahedra arranged in layers parallel to (100) and (ii) ZnO(2)(N/O)(2) tetrahedra located between the layers. Elemental analysis establishes the ammine-to-water ratio as 3:2. ZnO(2)(N/O)(2) tetrahedra are located at special position 4e (site symmetry 2) in C2/c. The two O atoms of ZnO(2)(N/O)(2) are bonded to neighbouring P atoms, forming two Zn-O-P linkages and connecting ZnO(2)(N/O)(2) tetrahedra with two adjacent bc plane layers. A noteworthy feature of the structure is the presence of NH(3) and H(2)O at the same crystallographic position and, consequently, qualitative changes in the pattern of hydrogen bonding and weaker N/O-H...O electrostatic interactions, as compared to two closely related structures.
