摘要

Crystal hydrate of sodium salt of an oxovanadium(IV) complex with nitrilo-tris-methylenephosphonic (NTP) acid Na-8[(VO)(2)(-O)(2){(VO)(3)-N(CH2PO3)(3)}(2)]20H(2)O is synthesized, isolated, and studied: space group P1, Z = 2, a = 12.5829(2) angstrom, b = 13.9297(2) angstrom, c = 15.1051(3) angstrom, = 72.233(2)degrees, = 76.907(2)degrees, = 70.388(2)degrees. The NTP ions are completely deprotonated and hexadentate. In coordinating the VO2+ ion each NTP ion closes three N-V-O-P-C cycles with a common N-V bond. By means of bridging vanadyl ions and oxo ligands the four-membered V-O-V-O cycle and the [-V-O-P-O-](4) macrocycle are closed. Coordination V polyhedra are distorted tetragonal pyramids. With regard to the occurrence of weak V-N bonds the polyhedra of two V atoms can be completed to strongly distorted octahedra.
