Abstract

Two polymorphs of zero-dimensional zinc phosphate with the formula, $0_{\infinity}[Zn(2,2'-bipy)(H_{2}PO_{4})_{2}]$, have been synthesized employing hydrothermal technique and their structure determined by single crystal X-ray diffraction. Both the structures consists of $Zn0_{3}N_{2}$ distorted trigonal-bipyramidal and $PO_{2}(OH)_{2}$ tetrahedral units linked through their vertices giving rise to a zero-dimensional molecular zinc phosphate. The structures are stabilized by extensive hydrogen bond interactions between zero-dimensional monomers. The structures display subtle differences in their packing created by hydrogen bond interactions. Crystal data: polymorph 1, triclinic, space group P1 over bar (No. 2), a = 7.5446(15) angstrom, b = 10.450(2) angstrom, c = 10.750(2) angstrom, \alpha = 67.32(3)$^{o}$, \beta = 81.67(3)$^{o}$, gamma = 69.29(3), V = 731.4(3) $A^{3}$, Z = 2; polymorph II, triclinic, space group P (1) over bar (No. 2), a = 8.664(1) angstrom, b = 8.849(2) angstrom, c = 10.113(2) angstrom, \alpha = 97.37$(2)^{o}$, \beta = 100.54(2)$^{o}$, \gamma = 100.98$(2)^{o}$, V = 737.5(3) $A^{3}$, Z = 2.
