Abstract

Izhodni molibdenovi(V) spojini, (PyH)5[MoOCl4(H2O)]3Cl2 in (PyH)[MoOBr4], smo reagirali s pikolinsko kislino v različnih topilnih sistemih. Za deprotonacijo kisline je bilo potrebno reakcijskim zmesem dodati bazo. Izolirane so bile tri nove koordinacijske spojine, ki vsebujejo koordiniran pikolinatni ion, nevtralna spojina [Mo2O4(Py)2(pic)2], ionska spojina (PyH)2[Mo2O4Cl2(pic)2]‧CH3CN ter analog slednje s propionitrilom, (PyH)2[Mo2O4Cl2(pic)2]‧CH3CH2CN. Pri reakcijah (PyH)5[MoOCl4(H2O)]3Cl2 s pirazinkarboksilno kislino je bil izoliran en sam produkt. Gre za ionsko spojino (PyH)2[Mo2O4Cl2(pyraCOO)2]‧CH3CN. Dvojedrni anion v tej spojini vsebuje pirazinkarboksilat, ki je koordiniran na molibden(V).

Secondary title:	Coordination chemistry of [MoVOCl4(H2O)]- with picolinate or pyrazinecarboxylate
Secondary abstract:	Starting molybdenum(V) materials, (PyH)5[MoOCl4(H2O)]3Cl2 in (PyH)[MoOBr4], were reacted with picolinic acid in different solvents. In order to deprotonate the acid, the reaction mixtures were added a base. As a result, three novel molybdenum(V) coordination compounds with picolinate were obtained: neutral [Mo2O4(Py)2(pic)2], ionic compound (PyH)2[Mo2O4Cl2(pic)2]‧CH3CN and propionitrile analogue of the latter, (PyH)2[Mo2O4Cl2(pic)2]‧CH3CH2CN. The reactions of (PyH)5[MoOCl4(H2O)]3Cl2 with pyrazinecarboxylate afforded a single compound, (PyH)2[Mo2O4Cl2(pyraCOO)2]‧CH3CN. The latter contains pyrazinecarboxylate which is coordinated to molybdenum(V).
